Once the device is notices, it's there forever. The exception is
the bitsy were we've started putting in stuff to take out pccards.
We need to move that work everywhere, just haven't gotten around
to it.

hi,
a 9p file server can be detached by clunk-ing the connection,
however there doesn't seem to be a way one can detach a kernel-
level driver?
there's devattach, devopen, devclose, etc, but the only thing
reminiscent of 'devdetach' is 'devremove', which of course is
different...
there is detach code in the bitsy kernel for the wavelan ethernet,
but nothing in /sys/src/9/pc...
do i assume that once bound a device cannot be 'unbound'? if
devremove the answer?
