How do I save _all_ relevant information about current video mode so
that I can restore it afterwards exactly as it was?

This problem comes from a Device Driver that is triggered and needs
some input from the user.  Therefore the screen gets blanked, user
input requested, some action taken, and afterwards the driver must
return to wherever the pc was running with the video mode completely
intact.

Anyone?
