Perhaps the video driver could allocate memory at a fixed physical address and always maintain the state there, and then at initialization time check for some magic numbers (do a checksum, etc.) to see whether a prior state existed. This would provide a warm reboot capability (as long as the system doesn't clear all memory at boot time.)
Of course, why anyone would design a board that can't be initialized is completely beyond me ...
