Unisntall Network PCI Card

[Jake Stride]

I have recently started using freebsd since the debacle with redhat, 
and have a question that I am not sure of the answer too.

I have a freebsd 4.8 machine running as a print server, and I wish to 
uninstall a network card from it (wi0). Can I just remove the card (and 
associated start_if.wi0 config file) and freebsd will work out the rest 
(In redhat kudzu would have done this for me). Or do I need to tell the 
kernel not to load the device anymore.

I have searched google to no avail, most people tend to have problems 
installing not uninstalling things.

Thanks

Jake
