I'm connecting to the servers that are running on colocated boxes from my
home network for testing. Here at home I'm on a cable Internet broadband
connection with about 6mb/s down and 1mb/s up.

It returns 7200. I'm not sure how that is measured, but is this a
measurement in seconds? If so, that could be the problem right there.

No, the clients that have been connecting to Firebird also have access to
Windows servers running FB 1.5.5 Super Server as well, and they are not
experiencing this timeout at all.
