penalvch, yes the enablement stack should work.  The patch set was
appropriately rejected by the kernel team, as the enablement kernel
would provide the same functionality.

I should have closed this bug out back then when the patchset was
rejected.

Title:
  xrandr offers more modes under 12.10 kernel (3.4) as under 12.04
  kernel (3.2)

Status in “linux” package in Ubuntu:
  Won't Fix

Bug description:
  It has been discovered that the number of modes available to xrandr in
  quantal is significantly more than those available in precise.  This
  is especially important in the case where the native resolution of two
  displays differ, and the displays need to be mirrored.  Such as in the
  case of connecting a laptop to an projector.
