What I had in mind with the above was the situation where a user tries
to reserve a region that is hardcoded into the BIOS, such as the address
of the BIOS text/data etc.

I don't think it would be a real problem anyway, if some user wants to
play with it, they have to take the risk of shooting themself in the
foot :)
