Comment 35 for bug 144077

Here is what I see in dmesg launching 10/12 Gutsy-RC live cd on my Thinkpad T41p with ATI Fire GL T2 Mobility:

[ 114.748000] [drm:radeon_cp_init] *ERROR* radeon_cp_init called without lock held
[ 114.748000] [drm:drm_unlock] *ERROR* Process 8080 using kernel context 0

glxinfo shows:
<snip>
name of display: :0.0
display: :0 screen: 0
direct rendering: No (If you want to find out why, try setting LIBGL_DEBUG=verbo
se)
server glx vendor string: SGI
server glx version string: 1.2
server glx extensions:
</snip>

So no acceleration for radeon. I will try the work around and see what happens.
