Indeed -- three major subsystems are of specific concern right now:

- i4bsd
- tty
- usb

Poul-Henning has expressed some interest in the tty code, and hopefully 
will do something about it sometime soon.  I'm happy to deal with if_slip 
and likely if_ppp once the tty code is done.  The various Cronys drivers 
are all waiting on the tty code, but otherwise appear ready.
