Without 2D-acceleration everything seems to work okay, but scrolling is uncomfortably slow. With acceleration enabled... Under 2.6.27.19, X runs okay. But the dmesg log gets these error messages when X start: [ 54.375769] [drm] Initialized drm 1.1.0 20060810 [ 54.441049] pci 0000:00:02.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16 [ 54.441521] pci 0000:00:02.0: setting latency timer to 64 [ 54.442380] [drm] Initialized i915 1.6.0 20060119 on minor 0 [ 54.543516] [drm:i915_getparam] *ERROR* Unknown parameter 5 [ 55.292058] [drm:i915_getparam] *ERROR* Unknown parameter 5 Under 2.6.28.7, X fails during startup and exits with an error message.

I have to reboot the machine to recover.
