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 ...
