I havent had a lot of time to pursue it, but I have seen several people
working on things to handle killswitches. The problem I've seen is that
several of them dont take into account features that the Dell notebooks
have: software configurable killswitches, and killswitch for cellular in
particular. 

Part of the problem would be that I dont know exactly who to talk to...

I wrote dellWirelessCtl. There was a patch a while back that integrated
it into HAL, but I didnt write that.
