Reading between your lines, I deduce that you do want to use a cable
to connect the two routers instead of WDS.
When going from an ethernet switch to another ethernet switch, one
*USUALLY* needs a cross-over ethernet cable. Same with going between
two computers. However, modern routers and switches all have an extra
crossover connector, an MDI/MDI-X switch, or automagic polarity
switching. I vaguely recall (not sure) that the WRT54G has automagic
polarity sensing and therefore does NOT require a crossover cable.

Yes. The easy way to tell for sure is to just insert an ordinary
ethernet CAT5 cable between the LAN ports on both WRT54G boxes. If
the front panel light turn on in the normal manner, you win and it
will work. If the front panel light stay off, you need a crossover
cable or adapter.
Incidentally, I sometime use this trick to test my ethernet cables.
One end of the cable goes to the crossover connector on the switch.
The other goes to any of the other jacks. If the lights come on, it's
wired correctly. Unfortunately, it doesn't check for split pairs and
flakey connections, but if I'm too lazy to dig out the cable tester,
this test will do.
I would not buy a long crossover cable. I build an adapter using a
cheap ($2) RJ45 jack, a short length of CAT5, and an RJ45 plug. The
RJ45 jack is wired for normal EIA-568B. The plug gets the creative
crossover wiring plan. With this adapter, I can take any ordinary
ethernet cable and convert it into a crossover cable.
