Help to find a wifi card working in adhoc under qnx632

Dear all,
I have been trying to find a commercial wifi card that could work well in adhoc mode under QNX 6.3.2. I have tried quite a few(the orinoco 11b pc card— work well in AP mode rather than in adhoc mode), and the list of supporting hardwares on qnx website seems not detailed enough. Appreciate if someone could provide me with any information on this.
