OK I've recompiled libdrm mesa and xf86-video-intel using their master
tree's and recompiled the head drm-intel-next branch of the kernel the
versions I were using before were only a few hours old

Good news X starts, bad news is the screen goes black once KDE starts
to load, pretty sure it's when the compositing is started

Another strange things happened, normally with KMS all my VTs are at
the laptops native resolution now they're in the top left corner at
what looks like 800x600 but not streched

Also when booting from a non-KMS but regular GEM kernel UXA doesn't
work now. I've had to switch back to EXA

I'm attaching my dmesg and Xorg log from the KMS retry

Could any of the problems be caused by:

[drm:i915_get_vblank_counter] *ERROR* trying to get vblank count for
disabled pipe 0


Cheers
