Actually, I have reports from reliable sources (I trust Alan to know how
to set up his BIOS :-) that this isn't the case and that even with
legacy mode on it doesn't work properly.  Same hardware works with no
modifications in LILO.  None of my test hardware can replicate the
problem, unfortunately and from my comparison of LILO and GRUB, there's
not an obvious problem.
