The patch below fixes the following to rivafb:

1 Seems that nVidia hardware has a limit on clipping coordinates that is
  also dependent on the color depth of the framebuffer.

2.From Pawel Goleniowski <pawelg@dabrowa.pl>: Fix for wrong colors at 16bpp
  (RGB565).  The fix has been submitted several times in lkml and this list
  but was never applied.

3 Search all I2C/DDC busses for the EDID block instead of just the first
  bus.

4 Updated request_mem_region/release_mem_region to
  pci_request_regions/pci_release_regions.
