Everything looks good to me with the exception of some issues I ran into
with terminal codes. Setting TERM=dumb before running fixed it, but we
might want to set that inside of DTS since I can't think of a reason why we
would need colors or any of the other "fancy" features of the vt220, and
setting everything to teletype mode should make our lives easier when
parsing output.

I think that later on it might make sense to have "CPU" be a device class
like NIC or Cryptodev, but that can be revisited once we get closer to
interacting with hardware.
