As mentioned yesterday, it's a Linksys WPC54G connecting to a Linksys
WRT54G running DD-WRT.

I'm wondering myself whether that's the basic nature of the problem.
This laptop has always been awful on wireless, under any OS, to any AP.
I'm wondering if it's just plain CPU-bound. (Or maybe IBM did
something stupid in the design of the PCMCIA slots, like they did with
Thinkpad 600 batteries.)
