That's ERROR_INVALID_FUNCTION.

means that the adapter *does* support monitor mode.

Somebody else had a similar problem:

        http://www.devsuperpage.com/search/Articles.aspx?G=8&ArtID=1645342

with some other driver with a "device driver" upper half and an NDIS lower half - they could get OIDs, but trying to 
set the OID_802_11_BSSID OID failed.

Do you know which call in the driver is failing?
