Can you re-initialize the device from scratch? My knowledge
about the video hardware dates to SVGA times and even that
is not too deep.

Maybe provide a basic SVGA re-initialization routine on x86 and have
an interface for the third-party in-kernel drivers that
would contain the re-initialization routine.
