Feedback is appreciated.

My AcerPower 1000 (Broadcom AF1) was hotter then the hinges of Hell and the cpufreqd worked like a charm. I assumed that the WiFi cards were causing the cpu to run harder? Quien Sabe?

1:07 PM EST 		Yeah, the notebook is an Averatec 3200. Definitely agree that it could be harnessed as a source of heat for anyone going cold this winter. ;)

Mine came with integrated Broadcom wireless. I have a wide array of wireless cards for my notebooks computers, ranging from rt2500 to rt61, even a couple of rt73USB options. I had rt73USB working like a champ after running a little script I cooked up.

#! /bin/sh -f echo 'blacklist rt2500usb' | sudo tee -a /etc/modprobe.d/blacklist

Now the rt2500 PCMCIA card runs fair enough, but the rt61 card, which uses rt61PCI in Gutsy, tends to get a bit warm. I found that it dramatically reduced network drops with the use of an Argus notebook cooling pad. But to be fair, these little AMD powered notebooks get pretty hot anyway.

Will swap out powernowd for cpufreqd. Also, I think cpufreqd needed some extra modules for throttling if memory serves? Did you find it needing anything extra?
