I continued using my desktop PC with intel G45 graphics, kernel and 
intel driver with pageflipping enabled and no hangs occurred. Everything seems 
to work fine.

I also compiled the intel 2D driver with pageflipping enabled on a notebook 
with intel GM965 graphics. I noticed an annoying issue: every few minutes 
(part of) the screen went black for an istant, maybe during a refresh. Then, I 
installed kernel 2.6.35 and this issue seems to be gone.

I hope more people could test it, but I believe it is safe to enable 
pageflipping in the intel xorg driver with kernel 2.6.35.
