The PCMICA-FBUS is not compatible with O2Micro Cardbus controller. But it is compatible with other cardbus controllers like TI, Ricoh, Toshiba, NEC, CL and etc. In this case, you have to choose another laptop if you want to use the PCMCIA-FBUS card.
At the same time, National Instruments will release a new PCMCIA-FBUS Series 2 card soon (this month), which is compatible with O2Micro cardbus controller.
