ifconfig ath0 list scan: lists numerous access points
including the one of which We're attempting to connect.

This is a good thing; working :-)

This is news to me, thank you.

Switch (all radios) is on, this is why the 'bluetooth'
led lights.

When you say 5416/5418 I'm assuming your speaking about
the Atheros device?  If so this machine has a 5212.

The above 'softled' knob had no affect.  there were at
least 2-other knobs that did have an affect on the
'led' only.  I'd rather concentrate on the tx/rx of the
device itself.  It now appears the device is partially
functioning because the 'list scan' sees other access
points nearby...

==> On this T61p mach-type 6459-CTO, here are the
sysctl knobs that have had a visible effect
(off/flicker/on) for the wireless nic led only (Atheros)
and not the bluetooth led.

Once I toggled these knobs the hardware switch was not
able to turn the led off again and neither were the
knobs that turned the wireless nic's led on.  I'll see
what happens after rebooting the machine; whether the
led returns to 'off'.

At this point I'll assume the device is working while
in FreeBSD and I'll try and configure WPA to see if
this is the current issue I need to resolve, that is
unless you see something here I have overlooked.
