Screen was almost freezed, cursor was stuck but the machine was alive and I was able to use SysRq to kill X and try to restart it (but that didn't help).
I don't remember anything similar in recent kernels (<= 2.6.37) and got this only once with 2.6.38-rcX.
Environment at the time of the GPU crash: KDE4 (without "Desktop Effects") Chromium Claws Mail Dolphin ccached make -j3 on a just pulled linux-tree (so I/O bound) SMPlayer/Mplayer (just launched)
Assorted logs attached.

I was experiencing intermittent hangs when starting mplayer earlier in this release cycle (on both a desktop with a G45 and a laptop with a GM45), but I haven't encountered them in quite a while. I don't know if they looked exactly like the above since all the hangs have been rotated out of my logs :(. I ended up concluding that it was actually a regression in xf86-video-intel rather than the kernel (but no real way of testing this), since there was a lot of Xv related churn in the driver around the time I was having the issues.
So you might want to try again with the latest git xf86-video-intel and see if it still happens.

xf86-video-intel bug or not the kernel should be able to reset the GPU I think... (I'm using KMS).
Anyway I'm using 2.6.38-rcX on this PC for a month, and it happened only once. This is the complete list of 2.6.38 based kernel I've used an when (login time):

Happened again today (two weeks later), always while starting a video in SMplayer/MPlayer.
