Hi Chris,

I have an Acer Aspire D150 and the LED hasn't been lit with FreeBSD, 9-rc3,
9-release or 10-current  (with BroadCom and 2 Atheros cards). it did work
with Fedora GNU/Linux 11. I did try setting in loader.conf as recommended
to me to no avail. On one hand it was easy to get the attitude "who cares
about the LED anyway" but on the other I'm thinking it's a simple little
thing that's important,I guess like maybe buying a new car and it's missing
a knob on the stereo. (?) :) I suppose it probably should work.
