In my previous post I mentioned that I got the wireless adapter in my Compaq R4100 series laptop working with ndiswrapper. It appears this was a total fluke, others have had to add "noapic" kernel parameters to get it working correctly. I found if I set this kernel parameter the wireless adapter wouldn't work at all; without it everything works normally.
