Upstream bug was solved with the following commit.  I'm going to re-
target this to the kernel team, so they can verify the fix is included
for natty and sru it to maverick if appropriate.  I am not seeing the
git commit id in the ubuntu-maverick git tree, but maybe its commit id
changed when it was backported.

    drm/i915: Retire any pending operations on the old scanout when
switching

    An old and oft reported bug, is that of the GPU hanging on a
    MI_WAIT_FOR_EVENT following a mode switch. The cause is that the GPU is
    waiting on a scanline counter on an inactive pipe, and so waits for a
    very long time until eventually the user reboots his machine.

    We can prevent this either by moving the WAIT into the kernel and
    thereby incurring considerable cost on every swapbuffers, or by waiting
    for the GPU to retire the last batch that accesses the framebuffer
    before installing a new one. As mode switches are much rarer than swap
    buffers, this looks like an easy choice.
