Merge branch 'i915fb' of git://git.kernel.org/pub/scm/linux/kernel/git/airlied/intelfb-2.6

* 'i915fb' of git://git.kernel.org/pub/scm/linux/kernel/git/airlied/intelfb-2.6: (25 commits)
  intelfb: fixup clock calculation debugging.
  Removed hard coded EDID buffer size.
  intelfb: use regular modedb table instead of VESA
  intelfb: use firmware EDID for mode database
  Revert "intelfb driver -- use the regular modedb table instead of the VESA"
  intelfb: int option fix
  sync modesetting code with X.org
  intelfb: align with changes from my X driver.
  intelfb driver -- use the regular modedb table instead of the VESA
  Adds support for 256MB aperture on 945 chipsets to the intelfb driver
  intelfb -- uses stride alignment of 64 on the 9xx chipsets.
  intelfb: some cleanups for intelfbhw
  intelfb: fixup pitch calculation like X does
  intelfb: fixup p calculation
  This patch makes a needlessly global struct static.
  intelfb: add i945GM support
  intelfb: fixup whitespace..
  intelfb: add hw cursor support for i9xx
  intelfb: make i915 modeset
  intelfb: add support for i945G
