Generally called "unreal mode". Yes, sure. Just a hack though.

The real mode on i386+ can actually access the whole 4GB address range due to
a former-bug-now-feature in the i386+. This "bug" causes the segment limit
to not be reset

say the last megabyte visible in real-mode.
What's the easiest way to have linux ignore the megabyte starting at 15M?
