Is it possible to set the link layer address on NICs in NetBSD?

Cursory examination of manpages/ifconfig/source doesn't seem
to indicate that this is possible right now in both 1.5.x and
-current.

If that's true:
1) is anyone currently working on it?
2) if the answer to question 1 is "no", would patches to support
   this be accepted?
3) if the answer to #2 is "yes", what's a good snap of i386-current
   to grab these days?  Is the HEAD reasonably stable?

thank you,
