I could never get WDS to work. Instead I have a/g waps all over the place like 
this, all running openwrt.


wap connected to ethernet:

               ______
192.168.1.x  |      |
ethernet-----|      |SSIDa=Joe_high 172.17.2.1
              |______|
                SSIDg
              =Joe_low
              (I may not have
               this one)



remote waps:

               ______
              |      |
              |      |client to Joe_high 172.17.2.x
              |______|
                SSIDg
              =Joe_low


The remote waps only connect to the outside world via 802.11a. There's no 
ethernet cable. You just need 120V and a spot to plunk the wap down. These waps 
get their IP from the wap that's connected to the ethernet.

802.11g clients all see the same SSID and get their dhcp from a box on the 
ethernet.

The networking/routing, getting packets back to the 802.11g clients, was a bit 
tricky. Bill had to help me with it, but once I saw what to do, it turned out to 
be only basic networking 101. I needed to add routes to 172.17.2.x on the boxes 
on the ethernet. (There may be one more layer of IP networks than I've depicted. 
It was a while ago now, it works, and I've forgotten the details of how I set it 
up. Sorry).

Joe
