P1 boxes are supposed to work.

Drivers are in userland, yes (with the rights they need). Portable? Hmm,
maybe you're mixing something up between Fiasco und L4Linux. Fiasco is
an L4 kernel, L4Linux an L4 program running on a kernel. So L4Linux can
contain drivers, or a driver can be a standalone L4 program offering the
hardware functionality to clients. So a driver is more or less as
portable as any other L4 program, i.e. depends on the used environment
