This is regression, thus I report it. Everything was working find about
month ago. This is clearly a driver problem, not a hardware problem!

This is not "very old", rather just "old" (Q2'04). I was able to run smoothly
gnome shell on similary old other intel chip (915GM, from Q1'05) in
laptop. Strange that similary equiped desktop chipset cannot do the same
(I can play in many 3D games on it without much problem). For me old is
something more like pre-2000. ;)


Thanks,
