I first discovered this problem when updating to 2.6.23 final on x86_64. When I launched google earth, the kernel paniced. When I tried to reproduce, it oopsed instead of panicing.
dri/drm seems to work generally, as I am running beryl without trouble, so far I could only reproduce the problem with google earth.
I have been using 2.6.23-rc6 for a while before, but I cannot tell if the problem already occured there. I am sure though that it wasn't there on 2.6.22(.Y). If anyone can tell me which commit might have caused this, I can revert it and test though.
I don't have a trace of the panic, but I can give you the oops:
