That would be a great thing... it's not that I really need the noise level (or 
the quality value), I was just testing how easy I can push values through 
nl80211 into userspace. The layer 1/2 data I'm looking for is signalstrength 
and transmission rate for each adhoc communication partner. And I still think 
the mac80211 stack is missing some easy way to get them at the moment.
