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.
