OK, sorry for the confusion, iwl4965 was not enabled by default, and I
assumed it was not there.
I've completed the test, wireless-testing kernel from two days ago
does not resolve the slow wireless connection.  I will update the bug
report with this data.

It's an old Wireless-B unit, so I can only guess it's 'B' only.  It is
a Linksys WAP11 Ver. 2.0
Firmware: v2.05, Aug. 04, 2003.  Unfortunately, the hotels and coffee
shops around the country are filled with these units, and I travel for
a living, so I'm holding out hopes for a solution, and stand ready to
help in any way I can.

Again, I will update the bug report with this data.
