Sorry about that. I set up one of those under Ubuntu for a friend on mine-- it wasn't fun. As far as I know, NDISWrapper is just about the only way to go about getting that up and running in linux. The problem I had with that, is that the windows .inf driver file is damn hard to find for that card.
If I remember correctly, I had to use the driver CD that came with the card and extract the .inf file from the .cab files somewhere on the cd. I'm sorry I can't be more specific, it was several months and 1000 miles ago that I did this. Just browse around the CD until you find a .ca files and try them all. Good luck.
Now, I think that these particular .cab files are InstallShield .cab files. in that case you will need to use the 'unshield' program to extract them. That source package can be found here: unshield Sourceforge page
A more in-depth installation page for NDISWrapper can be found on that packages Wiki:

Sorry to make the prospect seem so hopeless. It probably won't be as bad for you as it was for me. Best of luck getting your card up and running
P.S. Keep me posted, I'd like to know how you fare (and if you find another way to get that card running).
