The newer version of tcpreplay (>= 1.5beta6) can fake the conversion of a 802.11 packet dump to libpcap. more info here:

There is a tool included with aircrack called airdecap:

I believe its main purpose is to decrypt encrypted captures, but I believe it outputs them in a standard 802.1 pcap format. I have used it (at least the older one for Windows) and was able to read and filter the results in Ethereal.
