I'm making a *swag* on this. I'll bet your 'sdb' is called 'sdb1' or has 
a uuid given to it by the Ubuntu kernel. Open a terminal in Ubuntu and 
run `dmesg` (You can pipe to `grep` and search for sdb if you don't want 
to read the whole thing.) Find where the Ubuntu kernel recognizes and 
mounts sdb and see what it's called. Then you can edit all the stuff in 
your LFS to reflect that--fstab, udev, etc.

I'm caught in the nether world between "old" and "new" grub and don't 
know if the "new" grub starts counting at 0 or not. I too am running 
Ubuntu 10.04 LTS and preparing to do another LFS build. I think that 
it's important for you to change all the references to your flash drive 
in the appropriate files in your LFS. I don't think changing just grub 
will get you completely booted. It probably would get you far enough so 
that you could check some logs though.

Good luck.
