I suppose it would be possible to store the start and end block for the
most recently used partition in the screen holes with a check byte,
which would be reasonably efficient, since volume swapping is
infrequent.

Hmm, actually, even if it doesn't do this, it's a reasonable idea, and
a possible improvement over the scheme currently used on the CFFA

Thoughts?
