I'm also hitting this bug with yesterday's daily Karmic build on following hardware: Motherboard: DG45ID with intel X4500HD [G45]
I've booted the system with this live CD three times and every time the results have been different: 1st boot: KMS did work and Compiz started but Xorg was taking 100% CPU time and everything was running extremely slowly - like everything were software rendered. I guessed at that time that the daily build had a broken intel driver and did not investigate further. The performance was too slow to be usable. 2nd boot: KMS did fail and I saw the *ERROR* messages above in the dmesg output. Compiz would not start. Terminal (VT1) did not work because the screen mode was incorrectly set. 3rd boot: KMS did work and Compiz started. Everything seems to work just fine. However, I'm seeing this in the dmesg output: $ dmesg | grep drm [ 6.636985] [drm] Initialized drm 1.1.0 20060810 [ 6.785857] [drm] MTRR allocation failed. Graphics performance may suffer.
