[wplug] How does Debian connect devices to modules?

[Rick Reynolds]

My laptop has a wireless and a wired interface.  I think I'm using 
eth1394 as the module for the wired interface (eth0) and I know I'm 
using prism54 for the wireless (eth1).

Where or how does Debian map the device to the module?  How does it know 
to connect eth0 to eth1394 and eth1 to prism54?

I ask because I've just upgraded to Etch and also took the opportunity 
to try a few things that involved a recompile of the kernel.  Now for 
some reason, wireless doesn't work unless I'm in the port replicator 
(docked).  When undocked, I do an lsmod and I see the prism54 module 
loaded, but when I run iwconfig it reports no wireless extensions for 
eth1.  I have no idea why it is working when docked.

Thanks,
Rick Reynolds
