In my case for FC2 this works since I have just the one pcmcia interface card installed at a time.
I have used the prism54 driver almost since it turned up. It has worked fine with my 3CRWE154G72-card except for the latest versions with the 2.6 kernel.
It works OK as long as the traffic volume is low, but an FTP to a computer on the same LAN, or accessing a big file over NFS, make it halt. To recover I have to deactivate and then activate the card with the network manager. I.e. for casual web browsing it works, but not for file transfers. Do you, Scott, see any of this with your card?
By the way, I have heard that there are now 3CRWE154G72-cards out there that are not compatible with the prism54 driver... (mine is version 1.0)
