Bug#550977:

[Alberto Luaces <aluaces@udc.es>]

Hello,

I also happen to suffer from the same bug. Same card, the Mobility
Radeon 7500, but different laptop: ThinkPad R51.

glxgears works with a similar warning to the one already posted:

*********************************WARN_ONCE*********************************
File radeon_tcl.c function radeon_run_tcl_render line 499
Rendering was 79 commands larger than predicted size. We might overflow
command buffer.
***************************************************************************

Any other OpenGL program more complex than that, like Blender or
World Of Goo fails: sometimes freezes, sometimes segfaults... and then the
filesystem gets corrupt, so I can only reboot and launch fsck in order
to recover it.
