radvd actually does support DNS advertisement (but rtsol doesn't, so it 
doesn't matter).  The problem is, it doesn't work.  on 7-STABLE it dumps 
"Can't assign requested address."  I think it has something to do with 
if_bridge not having a link-local address (apparently the standards are 
ambiguous about link-local addresses on bridges).  To make rtadvd work, 
I had to tell it to advertise on bridge-member interfaces directly.
