Hi Jim,

Based on comment #8 it sounds like backporting upstream commit
055bf38d3d6069707e2d555cffdde629b8404ff2 to the Precise Ubuntu kernel at
least got you past the boot hang issue:

  commit 055bf38d3d6069707e2d555cffdde629b8404ff2
  Author: Alan Cox <a...@linux.intel.com>

    drm, gma500: Fix Cedarview boot failures in 3.3-rc

Assuming this is correct, I've built a Precise test kernel with commit
055bf38d3d6069707e2d555cffdde629b8404ff2 backported.  I've then disabled
CONFIG_STUB_POULSBO so that the psb_gfx driver is loaded by default for
devices which are supported by both drivers (this is more for bug
899244).  However, if this patch helps you out, I wanted to get users
from bug 899244 to test as well to ensure there are no nasty side
affects for others.  If you could please test this kernel for me it
would be much appreciated.

If this at least gets you past the boot issue, I can investigate
providing a full backported driver via our linux-backports-modules
package.  Thanks.
