Ok cool. Just to summarize, these seem to be the only drm patches which are
currently in your tree and not in our 2.6.32-drm33:

[-+] drm/radeon/kms: add additional quirk for Acer rv620 laptop
[-+] drm/i915: fixup pageflip ringbuffer commands for i8xx
[-+] drm/i915: i8xx also doesn't like multiple oustanding pageflips
[-+] drm/i915/edp: Flush the write before waiting for PLLs
[-+] drm/radeon/kms: disable MSI on IGP chips
[-+] drm/radeon/kms: don't enable MSIs on AGP boards
[-+] drm/radeon/kms: fix typo in radeon_compute_pll_gain
[-+] drm/radeon/kms/DCE3+: switch pads to ddc mode when going i2c
[-+] drm/radeon/kms: fix sideport detection on newer rs880 boards
[-+] drm: stop information leak of old kernel stack.

Does this look complete?

Thanks,
Stefan
