Having just updated my XO last night via USB I'd suggest that it's
useful too (olpc-upgrade wasn't even on my machine as far as I could
see, so it wasn't really an option).

BTW, work around for me was to do something like the following (keep in
mind, I am *not* sure what the implications of doing this are, this is
so the people who know can say "egads, don't do that" if I'm doing
something wrong):

Plug in the USB Key (MP3 player), hold X to get the firmware and then
the backup done.
When the machine starts showing the "failed to boot" unhappy-face,
interrupt and go to the OFW prompt (ok).
Manually boot from the USB key...

    boot u:\boot\OLPC.FTH

which lets the upgrade continue (at least for me).  That suggests it's
probably just something to do with timing or similar issues that
prevented the initial attempt to read the file from USB.

HTH,
Mike
