Ah, looks like Dave has set the no-UUID in the default/grub.d, and 
perhaps he needs to do that because suse uses disk-by-id instead. So 
he's having trouble because bios may start with different numbering 
system each time it boots, so it may not be (hd1,1) and it won't boot.
And chainloading may also 'run'. I mean booting won't run, numbering 
runs. (English is sure funny)

Dave, you may want to run this instead....

linux (hd1,1)/boot/vmlinuz-2.6.31-12-0.2-desktop root=/dev/sdb1 ro
initrd (hd1,1)/boot/initrd-2.6.31.12-0.2-desktop
boot


*BUT* before you do that, please check at grub prompt
search -f /boot/vmlinuz-2.6.31-12-0.2-desktop

If it gives you hd1,1, then proceed, bit if it gives say, hd2,1, then 
change above (hd1,1) to (hd2,1) BUT /dev/sdb1 remains unchanged.
