It looks like Charles and Dan nailed it.

My ISP seemed to be keying off of the MAC address.
When I spoofed the router's MAC address (as per Charles'
instructions below), it was able to get a good IP address.
It still bugs me, though, that the ISP WAS giving me an IP
address, just not a good one. I guess they just didn't want
to make it easy on me :)

Now, I guess I'll try figuring out how to get my ISP to accept
the new MAC address. Or, I guess I can just change the MAC address
as the router boots.

Thanks for the good ideas, gentlemen. And thanks to Charles
for the Dachstein release - wonderfully simple and easy to use.

Since you're getting much different DHCP data using linux instead of
windows, you might try to see if you can change some dhcp settings and get
something more similar to your working windows config.  First try removing
any dhcp client leases (in /var/state/dhcp)...shut down dhclient & restart
(svi dhclient stop/start).  If that doesn't work, try tricking the DHCP
server by giving your external interface the same MAC address as the card in
your windows box (just make sure you don't have both interfaces on the same
ethernet segment...things would get massively confused).  You can do this
with the ip command (ip link set eth0 address 00:80:c8:ca:ab:11)...repace
the MAC address with the right one, of course, and make sure you've cleared
any dhclient leases as well...
