Just tried it on a releng6 kernel w/ the "new iwi driver" from max and 
it doesn't freeze my system but it also does not seem to work right. 
OTOH tcpdump works fine so it's in the dstumbler code.  Not too 
surprised as it's probably been several years since I last ran it.  Will 
dig some more later.
