I believe that board has wifi on-board. It has caused kernel panic before for me.
The 173 driver is being loaded because you have a pre7xxx series card.
* I see I am mistaken, and it just has a proprietary wifi adapter, and one of the models comes with that installed.
I would still creep around the bios and turn off pretty much anything you know you will not be using (ie, cool and quiet... make sure that the chip which the wifi plugin at the end of the board uses is off etc).
