This is essentially what Sun does.  It's a passworded boot prom, but
the effect is the same.  However, keep in mind that once someone has
physical access to a machine, most of the security battle is already
lost.  They can always remove the disk drive and move it to another
machine, if they can't get around your password system.  I have been
taught to make the machine as secure as possible from dialin and
network attacks and let it go at that.  If the bad guy has physical
access, it's only a matter of time.
