Wifi card selection under QNX 6.3.2

I have been in trouble selecting a doable wifi pc card under QNX632. Though the website claims supporting orinoco, intel, d-link, broadcom. i only tried the lucent orinoco wifi card. It could work well in AP mode, but not in the adhoc mode. The other chipsets either are only chips, or the model number is unknown. What might be the ultimate selection in my case? It seems to me the only way left is to modify the orinoco bug. Even upgrade to 6.4.0, the ralink are also just chipsets instead of the PC Card interface, which is suitable for my PC104 stack. Any suggestions are appreciated.
