I have the exact same wireless laptop card. I got it to work using the ADM8211 drivers, all I had to do was install the kernel sources, make a symlink to the kernel source, and compile the driver. THen I just insmodded the 80211.o module and it worked fine. I did this on Mandrake 9.2 but that's almost identical to Red Hat anyway. If you still have that card and you havent figured something out, email me at
jloden@toughguy.net and I'll give you detailed instructions and I can even send you the drivers, I've got them on my server someplace. Alternatively, you can get a hold of me on AIM almost any time as HolisticDriving. I'm glad to help if I can, I'm going through the same thing right now trying to get wireless to work on my desktop and it's giving me migraines.
