I am running xorg 7.1.1 with the i810 driver 1.6.5 and the xorg-x11-server 1.1.1. I am also running compiz. Everything seems to be fine except that the mouse cursor disappears after suspend/resume. Nothing seems to be able to bring it back except a xserver restart. The problem goes away with the option SWCursor true but this seems to disable hardware acceleration. My system is FC6 with the latest updates on a Dell Latitude 505. The graphics card is a i855. Suspend worked reliably on this hardware in FC4.
Please upgrade to 1.7.2 first of all, and try that. If that still fails, upload a log file.
The bug's been fixed in 1.7.2. Thanks.
Closing.
