There is no firm rule that madwifi must break with the next kernel.  It 
depends on the changes made to the kernel.  In most cases madwifi keeps 
working.

I'm not comfortable with being a bottleneck.  There are more team 
members with commit privileges.

I've just committed a fix for the forthcoming 2.6.38 kernel, but it 
should not affect 2.6.36.

That's not enough.  Please enable some driver that requires the real 
wireless extensions.  CONFIG_IPW2100 should be OK.  You don't have to 
use it, but it's the only way to enable wireless extensions.

I don't think MadWifi will be even ported to cfg80211.

That's not surprising and it has nothing to do with me being lazy or 
something.  The check is there for a reason.
