Is your r200 3d driver built with kms support?

glxinfo report would give good idea where the problem is. dmesg shows that
problem is the fake enable of second texture unit that is done as workaround
for hw bug.

I am also affected by this. It is caused by incorrect fake texture handling in
CS checker or something. More and a possible "fix" (it just disables texture
checking) here: https://bugs.freedesktop.org/show_bug.cgi?id=25544

Enemy Territory starts up with KMS disabled, KMS enabled crashes with same
message as in comment #1. KMS enabled 3D acceleration in the game is very, very
slow: perhaps 1FPS. Direct rendering always says "yes" and mesa is in hardware
acceleration mode. GLXgears runs fine with KMS off and KMS on.

Same computer runs the game on Ubuntu 9.10 fine (on older drivers?) but Arch
with the newest drivers can't do it.

That's fixed. Is there still a problem here?

Yes, some time around the introduction of KMS, acceleration stopped working. I
had it fine on Debian before squeeze and Ubuntu Maveric but recently upgraded
to Natty and it stopped working. Starting compiz gives the old
GLX_EXT_texture_pixmap not available error. It also complains about GL version
1.4+ whereas glxinfo reports version 1.4

Latest updates on Debian squeeze have 3D acceleration bursting into life.

That should have been 2D. Also, it was openGL version 1.4 whereas this card
only supports 1.3 so everything is as it should be. glxgears still gives low
values for FPS. Compiz now works fine.

I wish
/usr/lib/nux/unity_support_test -p
was not such a well kept secret, it would have helped clear up a lot of
misconceptions.
