I'm being working out with building KDE environment recently. 
Now I need installing Xorg first. As the <The X Server Configuration HOWTO> says,
if I use radeon card ,then I need emerge radeon-ucode or linux-firmware package.
Then I need rebuild my kernel with External firmware blobs . My video card belongs
to radeon 4000 series, so I should add "radeon/R600_rlc.bin radeon/R700_rlc.bin" as
it says into  External firmware blobs . But when I make, it says that it can't find files that I specific..
Can anyone help?

I maintain http://en.gentoo-wiki.com/wiki/Radeon , which should sort you out.

If not, please post again & I'll update the article to be more helpful.

Thanks a lot ! But I used lspci -v | less, it printed vebose information, then I looked up carefullyfor my video card, but I did not find anything about R600,R700 or other like, I'm still not clearabout R*** things , is it chipset name?

No it's the gpu family.  Did you look at this link on James' page:

  http://en.wikipedia.org/wiki/Comparison_of_AMD_graphics_processing_units

Above each table it tells you which RXXX you should use, if your card is 
listed below.

Oh, I should use RV710, that is really a long distance from R600/R700.So should I add RV710_rlc.bin into External firmware blobs ?

Yes, exactly. The first time you were missing
CONFIG_EXTRA_FIRMWARE_DIR, it should point to /lib/firmware if you've
emerged radeon-ucode.

Yes,that's right, when I checked my .config file I found that CONFIG_EXTRA_FIRMWARE_DIRis /firmware, then I corrected it and emerge xorg-server and twm.Command "X -configure" executed successfully , it did generate /root/xorg.conf.new.After that I used "X -config  /root/xorg.conf.new" , then screen turned black andOS can't response to any input.Then I "cp /root/xorg.conf.new  /etc/X11/xorg.conf" and "startx",but the result didn't change, was OS crashed?

See if you can access it using ssh from another PC.  Then check 
/var/log/Xorg.0.log for any error messages.

I have checked my Xorg.0.log, there is no error message. I have a question,I read xorg.conf , I didn't find any area about Window Manage, so how xorg-server knowswhich WM to invoke when I use "X -config /etc/X11/xorg.conf" ?BTW, among my class I am the only one who uses Linux, so it's impossible to use ssh.

But when I use make , the error message like:make[1]: *** No rule to make target `firmware/radeon/R600_rlc.bin', needed by `firmware/radeon/R600_rlc.bin.gen.o'.  Stop.make: *** [firmware] Error 2
It's weird, because I think I have done all the Prerequisite correctly, so how could I 
fix it out ?

I think you need:

CONFIG_PREVENT_FIRMWARE_BUILD=y

Configured into your kernel.

Have a look at your dmesg output. It should have your Radeon card
version listed. Mine is a Radeon REDWOOD chip.

Here's my kernel config relating to building firmware into the kernel:

(ignore the fact that I wastefully build in all the chip versions other
than the REDWOOD)

CONFIG_PREVENT_FIRMWARE_BUILD=y
CONFIG_FIRMWARE_IN_KERNEL=y
CONFIG_EXTRA_FIRMWARE="radeon/REDWOOD_pfp.bin radeon/REDWOOD_rlc.bin \
radeon/REDWOOD_me.bin radeon/CEDAR_pfp.bin radeon/CEDAR_rlc.bin \
radeon/CEDAR_me.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 carl9170-1.fw"
CONFIG_EXTRA_FIRMWARE_DIR="/lib/firmware"

Window managers are started by users. I think you are talking about
"display managers".

Xorg runs a script /etc/X11/startDM.sh. It will start up /etc/init.d/xdm
if that's the display manager defined (as it is in a default Gentoo
setup). You define which display manager you want to start in
/etc/conf.d/xdm, for example:

DISPLAYMANAGER="kdm"

This will start the KDE4 display manager.
