[gentoo-user] Card is Radeon R200, but Mesa builds Gallium R300; HELP!

[Walter Dnes]

  Now what?  Ignore what you see on
http://www.gentoo.org/doc/en/xorg-config.xml and
http://www.gentoo.org/doc/en/ati-faq.xml about an
"ATI Technologies Inc RV280 [Radeon 9200 PRO]" not needing a binary blob.
It does require the R200 blob from radeon-ucode.  If the blob isn't
there, the bootup will delay for a minute, time out, and then continue.
If the R200 blob is in /lib/firmware/radeon, it'll load, regardles of
what i put in the kernel setup; e.g.


[d530][root][~] dmesg | grep R200
[    0.277947] [drm] Loading R200 Microcode

notwitstanding that the kernel is set up like so...
[d530][root][~] zcat /proc/config.gz | grep -i r300
CONFIG_EXTRA_FIRMWARE="radeon/R300_cp.bin"

  The question is... how do I force Mesa

(EE) AIGLX error: dlopen of /usr/lib/dri/r200_dri.so failed (/usr/lib/dri/r200_dri.so: cannot open shared object file: No such file or directory)

short... the R200 is not supported under Mesa Gallium.  So a glxgears
rating of 262 fps with the ATI Radeon R200 card gives stuttering useless
streaming video while the onboard Intel GPU is OK, even though it gives
60 fps under glxgears.

Most likely you have vertical sync on for the onboard Intel gpu which 
can explain why you see it limited to 60 fps (lcds usually run at 60Hz).

Please remind me, where do you set up vsync?

On mine it seems to be on by default:

 $ less /var/log/Xorg.0.log | grep -i vsync
[ 22796.516] (II) RADEON(0): SwapBuffers wait for vsync: enabled

Hm... I thought this was about Intel GPU but apparently I misread... 
anyhow, you can just 'emerge driconf' to adjust your settings. Otherwise 
google reveals:
