I don't know of any L4-based system, which supports this setup
out-of-the-box. IMO Genode [1] and L4Env [2] have all you need to
build such a system on your own: PS/2 drivers, USB HID drivers, and
frame buffer console/GUI.

Both options implicate some hacking on your part as multi-head
scenarios were not addressed so far.

BTW, Genode seemlessly supports several L4 kernels, namely OKL4,
Fiasco, and Pistachio. That's a nice feature if you're not certain
which kernel fits your needs best and want to postpone the final
decision :-)
