Bug Description
I'm afraid I can't give you any reproduction recipe more detailed than "my laptop seems to crash whenever my wife tries to switch to her user". It's a 15" PowerBook with this graphics card:
0000:00:10.0 VGA compatible controller: ATI Technologies Inc RV350 [Mobility Radeon 9600 M10]
Here's the syslog output from the crash:

By the way, this is with linux-image- 2.6.15- 18-powerpc 2.6.15-18.27. I'll try upgrading to current and see if that clears things up.
