Description of problem:
r128 GL is not working

Version-Release number of selected component (if applicable):
xorg-x11-6.8.2-1.FC3.13

How reproducible:
glxgears

Steps to Reproduce:
1.glxinfo
  
Actual results:
direct rendering: No

Expected results:
direct rendering: Yes

Additional info:
According to Xorg.0.log direct rendering is enabled
(II) R128(0): Direct rendering enabled

but dlopen()ing of libGL fails with unresolved symbol WRITE_DEPTH

This results in a 'working' GL, but r128 is still giving
warnings about

libGL warning: 3D driver claims to not support visual 0x24
libGL warning: 3D driver claims to not support visual 0x28
libGL warning: 3D driver claims to not support visual 0x2c
libGL warning: 3D driver claims to not support visual 0x30

Again, this seems to be false according to glxinfo

Is this fixed in FC4 ? If not, I'm willing to do some tests ...
