[geeks] Simple hotspot with RADIUS auth, using MAC authentication

[Patrick Giagnocavo]

OK, I can't believe that none of the openwrt/ddwrt/coova-ap firmware
loads don't have a way to do this ...

I have a pretty simple desire:

use MAC authentication, with the MACs checked against a RADIUS database

If MAC is in the database, permit access.

Everything I come across talks about setting up WPA2 with RADIUS, or
other EAP/PEAP/802.1whatever crap that I have no desire to futz with. 
Yes, we know it is not that secure, but then again we have open ethernet
ports with no kind of MAC security sitting around also.

Does anyone know of a simple way to set up the above, with any of the
various firmware for the WRTG54 series?
