Bug#475204: Ring buffer not flushed on Xorg startup (82945G/GZ)

Package: xserver-xorg-video-intel
Version: 2:2.2.1-1

I seem to have a similar problem with my video card, with regards to that
final error message at least (PRB0_HEAD and PRB0_TAIL indicate ring buffer
not flushed). The result of this is that the X server refuses to start (or
at least doesn't display anything on the screen). The situation is
preceded by my screen displaying random junk, and not updating (so I log
in remotely, kill the X server, try to restart, discover that it doesn't
work a few times over, then give up and reboot the computer). I suspect
this is due to out of memory errors -- the problem has cropped up in the
past when I've been running intensive programs on my computer, but don't
currently have any logs to back that up (I will try to remember the next
time it happens -- this is at least the second time I've come across it).

Here's the lspci specs for my video card:
00:00.0 Host bridge: Intel Corporation 82945G/GZ/P/PL Memory Controller
Hub (rev 02)
00:01.0 PCI bridge: Intel Corporation 82945G/GZ/P/PL PCI Express Root Port

I've attached my xorg.conf and Xorg.log from when I tried to restart the
