Ah ha!  That makes sense.  The only thing that doesn't make sense is 
that this card woks fine in another 2.6.8.1 Debian unstable system.  
What I find interesting is that lspci *does* show:

0000:03:00.0 Network controller: Intersil Corporation Intersil ISL3890 
[Prism GT/ Prism Duette] (rev 01)

That is correct.

scanpci, however, shows:

Harris Semiconductor D-Links DWL-g650 A1

That card, though, isn't inserted at the moment.  I did have a D-Link 
DCF-650W inserted previously (and have switched back and forth between 
it and the Netgear while trying to debug this problem). 

When I have the D-Link card installed, though, it doesn't show up with 
either lspci or scanpci.

Still think this is a problem with the prism54 driver, or something else 
entirely?
