I agree.

IMO, the ram at 0xf0000 needs to get migrated just like the rest of
the ram.
Silly example - Linux and APM. On Linux init, it finds the APM
vectors from bios and periodically calls them to sleep machine. On
migration, a new bios could have a different code location for apm -
if Linux calls sleep after migration it jumps into random code and
blows up.
