Okuji has done some fantastic work on an `ioprobe' command that has
overcome this hurdle. There's still more work to do, but it is now
feasible to correctly support both Mach and Linux-style partition
naming.
For those who are curious, ioprobe works by setting the trap flag,
then single-stepping through an INT13 call, scanning the machine code
for IO port usage, and recording the ports that were used. This
should be enough for us to determine the correct Mach or Linux-style
name for the device.
All in all, GRUB is developing very nicely.
