I tested out my Intel Prism 2.5 based card and it seems to work OK in
F9.
But be sure to have up-to-date firmware. My card started out with STA
1.5.6 and was _NOT_ happy with hostap in Fedora 9 at all, which isn't
unusual for such old firmware.
I flashed PRI 1.1.1 and STA 1.7.4 and it seems to be working quite a bit
better now. I'd suggest those versions since they will give you WPA
support too :) There have been reports that the 1.8.x STA firmware
isn't quite stable, so I'd suggest 1.7.4 for now.

I used pk010101.hex and sf010704.hex to flash the Intel card with. If
you do flash the card, make sure to you have NIC id 8013 like I do, the
firmware version you use is dependent on the NIC id. Of course I'm not
responsible if you fry the card :)
