ipw3945d, I assume?

That's probably the same thing I need (except / rw should be sufficient 
for me, so I think I can use /etc/modules.autoload).

I wonder if udev can be configured not to load the module. Probably the 
right thing is really to have ipw3945d run as regular service. It'd be 
nice if ipw3945 produced class net node for the device when the daemon 
isn't running, and just required the daemon to actually turn it on.
