dmesg with GPU lockup error

Blender doesn't work on my system. If I try to move the 3D blender scene with
the mouse the screen freezes, the cursor disappears and the system become
unusable for some seconds. The dmesg reports a "GPU lockup (waiting for
0x00002034 last fence id 0x00002030)" error.

My system configuration: 
Linux Slackware 13.37
Kernel 2.6.37.6 
libdrm-2.4.26 
mesa-7.11
xf86-video-ati-6.14.1
ATI Radeon 9100 (R200) AGP Video card

Steps to reproduce:

1. Start Blender 2.59:
$ blender

2. On the default scene with the cube, hold down the mouse wheel (middle mouse
button) and move the scene

3. A GPU lockup occurs quite immediately and the screen freezes.

The bug is very easy to reproduce on my system. 
Most of the time after few seconds I can use the system again (sometimes I have
to reset the system), but blender is unusable.
The same happens using blender 2.58a, 2.56, ...
