 You forgot to mention your laptop model. That information is valuable. Also
are you sure you haven't upgraded i810 Xorg driver as well?

 According to your explanation and your log this seems a BIOS related
problem. The driver stops working when it invokes int10 (BIOS) sometimes,
possibly because the kernel is doing some new optimisation which is giving
you a problem. I advice you to look at acpi4linux and investigate there.

  Is the crash a total (machine) freeze, like not pingable I guess not from
your explanation. In this case is the video POST method used that fails.
Test vbetools with are quite well integrated in the hibernate scripts.

  One last comment: maybe you could try the latest Xorg Intel 2.1 driver

This seems a BIOS problem + a video POST failure.

I don't think hot is a likely problem here.
