Good point: UUID= in /etc/fstab and grub.cfg

I don't see why at this point, but that's the problem when you cannot
test. I already have a custom initrd and recreating it is not going to
make any difference.
Actually, since I can't get qemu to work, I'm thinking of copying the
system on the USB stick to a DVD and see if I can boot off of that. If
it doesn't it could mean different things, but if it does boot then I'll
know that the USB stick is problably going to do likewise.

Good point, although machines that can boot off of a USB device are
likely to be fairly recent and should be happy with a 686 kernel.
Thanks for you comments.
