Not sure, can you be more specific on "modesetting" as 
grepping the /usr/src/linux/.config does not find anything,
so I'm not exactly sure what "modesetting" refers to....

Nothing under the "Generic Driver section of the kernels
I have been using has changed. The kernel worked before
I began following web pages and notes from this list
on removing hald and the hal flag from the system. I did
rebuild the kernel-2.6.36-gentoo-r5 after these
hal purge exercises began.....

CONFIG_UEVENT_HELPER_PATH="/sbin/hotplug"
# CONFIG_DEVTMPFS is not set
CONFIG_STANDALONE=y
CONFIG_PREVENT_FIRMWARE_BUILD=y
CONFIG_FW_LOADER=y
CONFIG_FIRMWARE_IN_KERNEL=y
CONFIG_EXTRA_FIRMWARE=""

Here are the setting from .config, as they always have
been: (I'd prefer not to use modsetting, unless provided
a GOOD reason to use it?)


CONFIG_UEVENT_HELPER_PATH="/sbin/hotplug"

I run an ATI HD5660 graphics card and use the open source Radeon driver
found in the kernel. When I select this driver, there's a second option
about allowing kernel modesetting by default. I've found that 3D
graphics and even the Xserver doesn't run on the 2.6.36 kernel unless
Kernel Modesetting is selected. This driver requires microcode to be
installed (emerge radeon-ucode). Now, I don't run an initramfs and
because kernel modesetting requires that the kernel handle the
framebuffer it loads the graphics driver before it has accessed any of
the system's hard drives. This means that for the kernel to find the
microcode it must be included when the kernel is compiled.

I can't help you further as I'm not sure what graphics card you run, nor
whether or not you're using the proprietary driver nor have you provided
the context for the error message provided in the subject.

I don't think HAL is your problem. Your kernel cannot find the microcode
for your graphics card. See above.

See CONFIG_EXTRA_FIRMWARE=""?

This needs to be where you place your filenames for your kernel
microcode required by your graphics card.

You should also have:

CONFIG_EXTRA_FIRMWARE_DIR=""

This should show the kernel the directory where your firmware is stored.
Mine is in /lib/firmware.

OK, I went and did a bunch of reading..... I do not use initramfs.
I emerge'd radeon-ucode

card:
02:00.0 VGA compatible controller: ATI Technologies Inc RV710 [Radeon HD 4350]
I use ati-drivers-10.11


> See CONFIG_EXTRA_FIRMWARE=""?

now says: 
CONFIG_PREVENT_FIRMWARE_BUILD=y
CONFIG_FW_LOADER=y
CONFIG_FIRMWARE_IN_KERNEL=y

and
CONFIG_EXTRA_FIRMWARE="/lib/firmware"

Then I copied all file with*710* matching from
/usr/src/linux/firmware/radeon/*710* to /lib/firemware

OK?

? not sure on this

I then emerged radeon-ucode-20101122
(but I'm using ati-drivers) ????
After the emerge I get:

* Your kernel has radeon DRM built-in but not the IRQ microcode.
 * For kernel modesetting to work, please set in kernel config
 * CONFIG_FIRMWARE_IN_KERNEL=y
 * CONFIG_EXTRA_FIRMWARE_DIR="/lib/firmware"
 * CONFIG_EXTRA_FIRMWARE="radeon/CEDAR_me.bin radeon/CEDAR_pfp.bin
radeon/CEDAR_rlc.bin radeon/CYPRESS_me.bin radeon/CYPRESS_pfp.bin
radeon/CYPRESS_rlc.bin radeon/JUNIPER_me.bin radeon/JUNIPER_pfp.bin
radeon/JUNIPER_rlc.bin radeon/R600_rlc.bin radeon/R700_rlc.bin
radeon/PALM_me.bin radeon/PALM_pfp.bin radeon/REDWOOD_me.bin
radeon/REDWOOD_pfp.bin radeon/REDWOOD_rlc.bin radeon/SUMO_rlc.bin"
 * You may skip microcode files for which no hardware is installed.

Those look to complete with the ati-driver driver?

YEP, I'm sure as hell confused now.....

I know I need kms with ati-drives, but all of the web pages
just seem to confuse me. Maybe 5-15 steps on kms with ati-drivers
is what I need?


What I find seems to confuse me more that help.....

Now I have ls /lib/firmware/

RV710_me.bin        RV710_me.bin.ihex    RV710_pfp.bin.gen.o
RV710_me.bin.gen.S  RV710_pfp.bin        RV710_pfp.bin.ihex
RV710_me.bin.gen.o  RV710_pfp.bin.gen.S  radeon


ls /lib/firmware/radeon/


CEDAR_me.bin    CYPRESS_pfp.bin  JUNIPER_rlc.bin  R700_rlc.bin     SUMO_rlc.bin
CEDAR_pfp.bin   CYPRESS_rlc.bin  PALM_me.bin      REDWOOD_me.bin
CEDAR_rlc.bin   JUNIPER_me.bin   PALM_pfp.bin     REDWOOD_pfp.bin
CYPRESS_me.bin  JUNIPER_pfp.bin  R600_rlc.bin     REDWOOD_rlc.bin


Before I emerge radeon-ucode, I tried it with just the lib/firmware
files. I think I need to select one file name out of that dir
for the parameter CONFIG_EXTRA_FIRMWARE=""?


but which one?

Since I use ati-drivers, I should unmerge radeon-ucode ?

All the instructions you received assume that you were using 
xf86-video-ati, *not* ati-drivers (also known as "AMD Catalyst for 
Linux", AMD's proprietary binary driver for Radeon cards).

Do *not* install any firmware files and make sure you disable the radeon 
driver completely in the kernel.  Not only KMS, but no driver *at all*.

Lesson well learned.....

Any other suggestions?

Ati-drivers is working again.
