One known bug is that there's a general interrupt sharing
bug.. interrupt sharing between interrupts above splhigh() (the modem,
running at splhigh()) and below splhigh() (the ethernet side) is not
likely to work.

There's some chance of things working if the ethernet interface is
ifconfig'ed down before you attempt to use the modem.
