Another good place for help with freebsd on arm is the #bsdmips channel
on efnet, if you're an irc-using kind of person.  Don't let the 'mips'
in the name throw you, it's the channel where the arm, powerpc, and
mips developers hang out.

Oh, and of course, there is also the freebsd-arm_at_ mailing list.
