Adding to this...
If you reflash the wrt54gs with the DD-WRT opensource image, I know it has radius authentication as
well as WDS to combine the access points. That way a user just picks one wireless network and will
roam on the access points.

I don't know of the capabilities of the WRT54Gs but here's what I would do:
Use 802.1x WPA/WPA2 capable APs and connect them to the switch. I have
been successful (though not entirely happy) with USR's 5461 Wireless
routers. Their 5451 Wireless AP's do not support 802.1x, but their
website at one time said they did.
Configure your APs or routers, and your RADIUS server appropriately
Configure m0n0wall to allow RADIUS traffic to the RADIUS server from
each of the APs
Configure 802.1x clients
This way, you have RADIUS authentication like you were looking for but
you also have STRONG encryption.
People can not capture login and password info etc. You are not using a
shared key (as with WEP). You and your client may sleep easy.
Now, you may ALSO enable the captive portal, but not require a
long/password on the captive portal page since a user being directed to
is has already authenticated to your RADIUS server.
My $0.02 Hope this helps
