(needed to install firmware-linux-nonfree) Strange as other ncurses apps I had weren't similarly affected. Whatever. Now I'm up and cooking with gas. If I can just get the new shortcut keys figured out...

radeon is the ATI(AMD) video chipset driver, not the radio driver. The driver tries to download vendor microcode to the video chipset when the system starts and my debian install (squeeze) didn't include the microcode. Other than kismet, I didn't notice any video problems though.

kismet client was slow before it even got to the point of starting the server. The rest of the system ran fine, no issues. I started looking at the dmesg video section just on a hunch and found where it was failing to load the firmware. Install it and then restarted the system. All systems go from then on.
