Right.  Already tried that.

OK, so I've got to get the sources for ivtv and follow that path.  That 
makes sense, actually. :-)  (I already had them, but ran into problems, so 
went back to the pre-packaged ones from the atrpms site - that would seem 
to be my mistake).

Nope, the kernel is loading the madwifi (ath_pci, wlan, etc) modules for my 
WG311, no problem.  Although, granted, it does look like that would be the 
problem from the depmod output - perhaps the pointers moved, which would 
make sense based upon your hint about how the modules are made.

Thank you very much for your fast response.  Much appreciated!
