I have yet to play with it, but my understanding was Plymouth was
reliant on kernel mode setting. The geode doesn't do that, but on XOs
we do seem to have full 1400x900 resolution for the terminals, so I'm
not sure if they will play well together. I've meant to try out
plymouth, this seems to be pretty good motivation.
