Did you check if it is really transmitting and receiving?  I.e. can you
associate and use the wireless network with the switch in the OFF position?

AFAIK, it is hardware driven.  On the T43, it's bios equivalent switch does
something to the IPW2915 card that causes the Intel driver to flag that a
hardware rf kill switch is active (and you cannot override that).

Lenovo is not IBM, and doesn't even come close.  I wish I could say they are
working at it, but I don't see that, either.

It won't, but see if the wireless card driver has a rfkill sysfs attribute
(Intel cards should), and what it says.
