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

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.....
