You may very well have the same symptoms on an i945. It just that
debugging is much easier if we keep the bug reports for different
chipsets separate, and debugging is really our goal here. Please ssh
into the machine and get a backtrace (or more importantly a GPU dump
as described in this bug report). But please upload it to a separate
bug report. If it turns out to be a duplicate of some other bug, it
can be marked as such. If it doesn't add any new information to that
duplicate bug it avoids having lots of redundant information in the
bug report, and any new information can be added in a comment to that
other report. Our goal here is to keep the bug reports simple, since
that makes debugging easier.

You have GM45 chipset. Some of the newer chipsets don't list the
numbers and names in the lspci, so I prefer to look in Xorg.0.log.
