These issues were why I originally switched from grub to extlinux.
While I can think of cases that would still break under extlinux, I
haven't run into them.  Mostly it was grub's device.map not matching
after the BIOS shuffled (or didn't) the disk order to boot sdb.
extlinux doesn't *have* a device.map, so it Just Works.
