Marcelo isn't currently online due to an accident, but I talked to

stabilizing the current code for use on the OLPC board.
Open source being what it is, I'm sure somebody will add the page
cache stuff and the adaptive ccache bits. Especially if they have
a stable base to work from :)
We've talked on and off about allowing some limited swapping to the
flash under emergency circumstances. But no one has come along with a
concrete way to do that yet.
I think its already done. When compressed cache reaches its size limit
(set by user), pages as sent to swap disks.
But, if you meant handling wear leveling issues (and maybe others) for
swapping over flash, then that is not yet done :) The usual swapping
code is still used which aims to minimize disk seeks.
