i suspect we all agree that this is the right longer term goal,
modulo the space and performance constraints on XO-1 that you
noted.

shorter term, fedora doesn't have many (most?) of our
platform-level changes (even for XO-1), so we're constrained to
shipping a "custom" kernel.  plus, no immediate release for the
XO-1 is even on the drawing board.  so, while we're trying to
keep the kernel differences for the two boards neatly segregated,
and hopefully in a way that it can all someday be turned into a
runtime decision, it's not a runtime decision right now.
