I am the Penguin
It turns out that the trick was to ignore the linux-wlan-ng download that pops up on most Google searches and go with the preconfigured packages (RPMS) put together for the Red Hat distros by an RPM packager in Raleigh, Tim Miller, who I will soon be recommending to the Vatican for beatification.
Make sure you read the README, and keep in mind that as usual, the programmer/guru tells you everything you need to know, but not exactly what you need to do or what you should expect. I would add the following directions:
1. Figure out which version and kernel of Red Hat you're running. Do this by firing up a terminal (System Tools / Terminal) and typing cat /proc/version.
2. Click on the appropriate Red Hat version (7.3, 8, or 9) found under Serve up the packages! Download the appropriate three packages, as indicated by your wireless card/adapter and kernel number.
3. Install each package separately. Do this by finding where you saved the RPM files, then right-clicking on the first file. Select Open With, then Install Packages. Click continue to complete the installation of the package. You'll do this three times, once for each package.
4. Edit the file as directed in the README. It's just the one change in the first file, followed by the renaming of the second file.
5. Stick your PCMCIA card in. Don't reboot or anything, and don't expect a happy little beep or a message telling you that new hardware has been found. Nothing happens.
6. Fire up Mozilla - Internet/Web Browser - then type in a web address. Watch in shock and delight as it actually appears.
7. Phone your friends. Post on your blog. Cackle madly and gesture rudely in the direction of Redmond.
8. Celebrate. You're driving the tank!
