Kismet shouldn't care, but it's likely the drivers dont' pass data packets properly. I'm not sure any driver on linux supports 11n sniffing properly at the moment.

Try capturing from the wlanXmon interface at the same time using tcpdump; if you see data packets in there that kismet is not seeing, post the pcap file and I'll take a look to see why kismet isn't processing them. I'm going to bet you won't see any data packets in tcpdump either, however.
