Now you make me really confuse, so you use the same system, but work in
the office but not home? 2.6.39.1 already has split driver, so
"iwlcore.ko" not exist anymore, and it will not affect the led behavior.

what module parameters you have in the system, could you do the
following:
$modinfo iwlagn
$modinfo iwlcore

you should see the list of supported module parameters in iwlagn, but
not iwlcore.

Thanks
