Dear Dave and others: I seem to hit a sudden regression in 2.6.34-rc1: the modeset fails. On this box it also means, no way to start X, which is unfortunate.
Here's a quote from bad dmesg (truncated front and back for brievity): Linux agpgart interface v0.103 agpgart-intel 0000:00:00.0: Intel HD Graphics Chipset agpgart-intel 0000:00:00.0: detected 131068K stolen memory agpgart-intel 0000:00:00.0: AGP aperture is 256M @ 0xd0000000 tpm_tis 00:09: 1.2 TPM (device-id 0xB, rev-id 16) Serial: 8250/16550 driver, 4 ports, IRQ sharing enabled ................ udev: starting version 151 [drm] Initialized drm 1.1.0 20060810 i915 0000:00:02.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16 i915 0000:00:02.0: setting latency timer to 64 alloc irq_desc for 33 on node -1 alloc kstat_irqs on node -1 i915 0000:00:02.0: irq 33 for MSI/MSI-X [drm] set up 127M of stolen space [drm:i915_gem_init_ringbuffer] *ERROR* Ring head not reset to zero ctl ffffffff head ffffffff tail ffffffff start ffffffff [drm:i915_gem_init_ringbuffer] *ERROR* Ring head forced to zero ctl ffffffff head ffffffff tail ffffffff start ffffffff [drm:i915_gem_init_ringbuffer] *ERROR* Ring initialization failed ctl ffffffff head ffffffff tail ffffffff start ffffffff [drm:i915_driver_load] *ERROR* failed to init modeset i915: probe of 0000:00:02.0 failed with error -5 dracut: Starting plymouth daemon Here's old one from 2.6.33: Linux agpgart interface v0.103 agpgart-intel 0000:00:00.0: Intel Ironlake/D Chipset agpgart-intel 0000:00:00.0: detected 131068K stolen memory agpgart-intel 0000:00:00.0: AGP aperture is 256M @ 0xd0000000 [drm] Initialized drm 1.1.0 20060810 Serial: 8250/16550 driver, 4 ports, IRQ sharing enabled ..........

No idea what went bad, so far, sorry. I'll try to bisect or otherwise find out.
