The driver for the at76c503a is on hold until I get some legal issues resolved. I got some windows source code to peruse while writing the driver, and I'm not sure if I'm allowed to or not.
So this thing is on hold until I get written confirmation from the legal owner of the code that I am allowed to write a GPL'ed driver, while perusing the windows source code.
Asked Jean Tourrilhes to update the entry in the Wireless HOWTO with the newly supported 3Com card. I just love it when a driver works... :)
