rEFIt was able to get me the Grub on the USB disk and I got the normal
list of kernels to boot into. The root= option comes into the picture
when you ask Grub to boot a particular kernel. So I had to correct that
before I could boot into Debian.

Grub version..... I haven't checked but I have a strong feeling that it
wasn't the Grub2 version. I will check it and reply back in a little while.

Oh, and the problem with root= might be solved using the UUID stuff
Ubuntu uses. How does go using UUID with Grub? Don't know yet :)
