Sorry about the subject screw up. That's twice in two days :-(
I know that downgrade is hard. The great thing is that the XO supports
that very elegantly right now!
I don't want to lose that.
It saved me once when I upgraded to joyride image without a developer
key (doh!) and was locked out.

downgrade is _very_ difficult to get right. it's a worthy goal,
but given our testing resources, and the natural concentration of
both developers and testers on the upgrade scenario, i wouldn't
promise downgrade. (and from what cscott has said to me every time
i mutter under my breath about upgrade oddness, i'm under the
impression that the "boot to previous version" is really only
a failsafe mechanism to keep the box running until your upgrade
is successful, and isn't intended as a true "downgrade". correct
me if i'm wrong, scott.)
