I completely agree.

I assume you meant lspci:

Actually, this is interesting and (so far) unexplained. I did not
intentionally ask the system to load ath_pci but it has done that. It
appears that ath_pci may have grabbed to hardware and hence stopped
ndiswrapper from using the card? No wonder I'm told that wlan0 doesn't
exist!

Sector9 ~ # iwconfig

eth0      no wireless extensions.

eth1      no wireless extensions.

So, then I have two questions:

1) What is the proper way to configure this card using ath0, assuming
it actually is supported?

2) If the above data is about my card then why isn't is coming up
802.11g? I get .11g support from ndiswrapper, or did when it
worked...)

I do have madwifi installed but I'm not intentionally trying to run
it, as far as I know:
