Is there a way to know how much more memory each option rom needs? If
so, you can correctly account for the extra memory you need. This would
be an ideal fix to this problem.

I do not know of a way to get this info.  It can change based on the
QEMU version.

Indeed it would be fragile to rely on a fixed size for each option rom,
given that they come out of the QEMU tree and can change at any time.

Only having dipped into this thread so far it seems to me we need some
way for qemu to communicate the result of its manipulations of maxmem
into the migration stream explicitly to be picked up by the other end.

Totally agreed.
