These people have Erlang running directly on the Xen hypervisor:

I've been working on my own non-serious-very-much-a-toy project to
build an OS in Erlang, running on Linux.  (i.e. Erlang is the only
non-system process running; everything the user sees goes through the
Erlang VM.)  I only mention it because you might find the same general
approach suitable: keep Linux around, just to provide the services
Erlang needs (including those you haven't implemented yet; e.g. native
TCP).  Linux can be VERY efficient when it's running primarily a
single process, so you're not really losing performance that way.
