I haven't looked at the Atheros driver code, but my understanding is
that this is an "unintended consequence" of the way the Atheros
driver / BPF interface is implemented; I'm not aware of any
immediate plans to change that code, so it's probably a safer bet to
change the libpcap code, unless we find a lot of other bits of code
that are broken by this ... quirk.

That was the problem.
Interesting that this only affects the Atheros systems. I had a
friend try on a Broadcom based Intel Mac and it didn't exhibit the
same issue, although he does have a "wlt" interface. Must be
something specific to the Atheros driver's implementation of the
monitor mode bits.
Can someone comment on whether this is expected behavior? ;)

P.S. Thanks for the replies Matt. ;)

I'm not sure what's causing this... but it definitely looks like
a bug.
Has anyone seen this before?
I'm using BPF and calling network IOCTLs... so I'm pretty sure
it's something in there, but I haven't been able to locate the
exact issue yet.
Any lurkers privy to the inner workings of the Atheros Airport
driver?
Try applying this patch:

(explanation is provided in a comment inside the patch.)
