We need backtraces for the crashes.

As for the DRI instabilities, see if not changing the default AGP settings makes
a difference.

I recompiled Neverball and Trackballs with -g3 and ran them through gdb but all 
I got was this, which doesn't tell you very much, does it?

0xffffe410 in __kernel_vsyscall

Do I need to recompile Xorg or SDL or something else with debug symbols? Sorry, 
I can code but debugging is something I was never really taught properly.

Thanks for the DRI tip, will try that soon.

Ah sorry, ignore all that, I was being stupid. Here's the backtrace from 
Neverball.

I just recompiled Mesa with debug symbols as well. This might tell you a bit 
more.

Changing product as this seems to be a Mesa issue. If you have backtraces for
the X server crashes as well, please attach them to another bug.

Actually, this looks like a duplicate of bug 5185, which has been fixed in Mesa
CVS. Please attach backtraces for the X server crashes (and change the
product/component fields back) or resolve as duplicate.

Mesa CVS fixed everything, thanks a lot. But I don't know which bug this is a 
duplicate of because you gave the ID for this bug.

Whoops, thanks for verifying this!
