It's a G45 intel chipset, GMA x4500 video Anholt recently sent in some patches, VSync is working for me now. I just booted my kernel with PCI=NOMSI, and it's very harder to reproduce now, unless I put my CPU under load by playing HD h264 video and have it draw subtitles. They sometimes render incorrectly, before X locks. It won't do it anymore on SD stuff.
I started having problems past intel 2.4.1 drivers, with the GEM kernel. I'm hoping this will work for 2.6.28 so I can start running stable releases of components instead of stuff built from GIT.
