This emulator has also been ported to the kernel, but I doubt that patch 
is ever going to get included.

As an alternative, somebody skilled could implement a two-stage resume 
code where all devices except graphics card get resumed normally, a 
usermode helper (standalone x86 emulator) is called to boot the graphics 
BIOS, after that the graphics card is resumed and resume continues 
normally to unfreeze all of userspace. Once this infrastructure is in 
place, it can also be used to boot video BIOSes on non-x86 platforms.
