	I switched to my Ubuntu 9.10 and looked at grub.cfg which is 
real weird! But here is a snippet from it:

	initrd /boot/initrd.img-2.6.28-11-generic
menuentry "Ubuntu 9.04, memtest86+ (on /dev/sda9)" {
	insmod ext2
	set root=(hd0,9)
	search --no-floppy --fs-uuid --set 
	linux /boot/memtest86+.bin

Notice it says 9.04 (on /dev/sda9) then set root=(hd0,9) which 
is an error when using grub-1.

	Why they do this is anyones guess!
