Erm... that's kinda horrible :-/

A couple of questions then.

1) Does the system BIOS offer a way to select one mode or the other? If so, no
point in adding it here if a reboot is required.

2) Where Toshiba supports this (Windows?) is a reboot required?

Rather than having to reboot, would a userspace mapping possibly be preferable?
Could be done without a reboot.

Finally, if we keep this, we need to print something to the system log
indicating success - and that a reboot is required to take effect.
