I'm not even sure you'd need a router. You may just need the switch
****tion of your WRT54G. You may need to disable the wrt54g's dhcp
server to maximize your chances for success (when I've done this
before I was actually on a dumb hub).
If you are using Windows on at least one computer, Internet Conenction
Sharing with the Windows computer tethered to the phone is what I've
done in the past on a GSM phone. It's pretty darned simple too. You
just enable internet connection sharing on the dialup or network
connection that the tethering uses, computers on the same lan will
start getting ip addresses from the ICS computer, and stuff will just
magically work (even if the client machines are Linux).
I'm not sure how to do an ICS equivalent in Linux, though I strongly
suspect there has to be a way.

I don't think there's a notion of "bonding" with GPRS. You could
segment the traffic though by having just one or two computers on each
network. You might need to get your hands on another switch or hub
though. Or, I wonder if you had two phones tethered to the ICS
computer what the route table would look like. Could be Windows would
load balance traffic between the two, I'm not sure. You might need to
fiddle with route priorities manually.
