 I've not been following this whole thread, so apologies if you've
already answered the questions below.

 Do you know if your bios can boot from an external disk ?  You might
have to go through the bios settings to make it possible.

 If the answer to that is yes, google has a lot of people asking
questons about doing this, and not many relevant answers.  Possibly,
passing a rootdelay argument to grub might help, see
http://www.reactivated.net/weblog/archives/2005/11/booting-linux-userland-from-an-external-usb-flash-disk/
(yes, I know ithat site is about booting from flash, but it might be
worth trying).

 Other than that, make sure that all your usb requirements are built
in to the kernel (EHCI|OHCI|UHCI USB_STORAGE, BLK_DEV_SD).
