Problem Description:

Before 2.6.29-rc2, I couldn't even run Xorg without having some garbled fonts
and gtk widgets (like http://molly.corsac.net/~corsac/screen.png)

Starting 2.6.29-rc2 (and the drm-next merge I guess) I can know run Xorg, but I
still have various problems:
- X cursor is garbled (can make a screenshot later if needed)
- at start, I have some WARNINGs:

And trying to restart Xorg for some reason, it fails (the screen is blocked at
the moment) and I have in Xorg.0.log:

Jan 17 16:51:47 hidalgo kernel: [  533.088113] [drm:i915_wait_irq] *ERROR*
EBUSY -- rec: 1 emitted: 2


with in dmesg:

[  533.088113] [drm:i915_wait_irq] *ERROR* EBUSY -- rec: 1 emitted: 2

and no vt switch is possible atm.

If you need more info, please ask.

xorg.conf follows:

Section "Device"
  Driver  "intel"
  BusId   "PCI:0:2:0"
  Identifier  "intel"
  Option "FramebufferCompression" "on"
  Option "Legacy3D"  "false"
  Option "AccelMethod" "UXA"
  Option "XvPreferOverlay" "on"
  Option "XvMC" "on"
EndSection

I'll try without any xorg.conf.
