It's more a problem with your card firmware/driver. What card/driver do you have ? In IBSS mode, all stations are required to send beacons. The protocol is a bit complex to arrange that, every 102.4ms, a station is chosen to emit the beacon. Receiving beacons from a station is enough to reset its timer, so with a properly functioning station, this timer does not expire. Unfortunately, in the wild, nobody test that IBSS beacons are generated, because without them, an open IBSS still appear to work...
