This is an issue with how GRUB deals with a FUBAR BIOS, and not 
necessarily a core GRUB design flaw. 

Syslinux, seems to win hands down (IMO) when it comes to dealing with
flacky BIOS's, but it's not because it's a dynamic loading design; it's
because HPA knew enough and spent the time refining that 1% of the
program that deals with bad BIOSes.

Should HPA and Werner take a day of their time to review and
correct GRUB, I'm sure this issue would vanish overnight.

Where GRUB struggles LILO throws up brickwalls.

Coolest thing is the world you can do with grub:
	Load a *partition* as your initrd
With this in mind it makes using images/archives for initrd for
non-embedded systems seem rather clunky. It's much cleaner
to just have an 8/16/32MB partition you dedicate to initrd. Users of
GRUB have been able to do this for YEARS.

And something to say here: Yes I hate lilo, but not because I think
Werner coded it lousy. A boot loader that uses a static block offset
to find it's target is a bad idea, that should have died with M$-DOS.

That said, it's still a wonder to me why GRUB, or another loader similar
in approach, was not adopted as the 'prefered' linux loader years ago.
