It is not as unusable as it was when I couldn't type anymore, but everything gets definitely very slow after a restart of X or after switching to a vty and back. Didn't try suspend/resume though. The controller says it's a: Intel Q35 SVGA controller. Maybe it's of interest that the machine is a HP Compaq dc7800 Convertible Minitower... Thanks for looking into the problem - tell me if/how i can help with debugging (there are a couple of FreeBSD users with this same canfiguration here which will be very happy about a well working FreeBSD 8 release :-)) Mat
