"My" patch is definitely needed to make the X intel driver work with 2.6.28-
rc1. Its a patch for X and not for the kernel.
Its not necessarily directly related to what you reported, but to:

It might also help to work with suspend, because seemingly (according to Intel
people) its not expected that the driver works with that bug.
So try the patch I posted (which is out of the upstream development version)
to make X work with 2.6.28-rc1 and continue testing if X works with 2.6.28-
rcx.
