I get what seems to be the same bug (at least, an strace shows it hammering
getparam, and I can't reproduce it with NO-TCL), but it usually doesn't happen
immediately, and I haven't yet reproduced it with glxgears (StepMania and
icculus-quake2 seem to do a fine job if left running for a bit, though those are
far from ideal testcases). I can regain limited control over the system with
magic SysRQ (unraw + kill), but only enough to cleanly reboot.

Søren, how did you get that stack trace? If I try to attach gdb to my X server
when this happens, gdb just hangs.

Also, in case this is a hw-dependent bug, lspci has this to say about the card
(it may be worth noting that it identifies as a Radeon LE / R200QL despite the
fact that the card itself is labeled as a regular 8500...):

and the AGP bridge (VIA KT400, any way to get a revision / stepping or similar?):
