Looks like you're using mac80211 drivers.

Either drop back to pre-mac80211, or go to the bleeding edge of mac80211 - 2.6.28, or better, 2.6.28+wireless-compat.

While it's getting much better, mac80211 has had a lot of thrash and they've broken rfmon on several chipsets in this way, I don't know if it's fixed on yours yet but that's how you'd find out.
