What you need is the #bsdmips irc channel on efnet.  Don't let the mips
in the name fool you, all the freebsd-arm developers hang out there. 
 Just drop in and start asking questions (and be patient with the fact
that although there are 80 people hanging out there, most of us are
either asleep or at $work depending on continent, and sometimes answers
come long after the question).
