2 Broadcom wifi cards in same laptop - Get both working?

Ok…I have an acer aspire 3000 series with a built in broadcom wifi mini pci card currently using ndiswrapper with no issues. I have purchased a netgear wn511b wireless-n pcmcia card which ALSO uses the broadcom chipset. I have the option of using ndiswrapper, the bcm43xx drivers now available in the kernel or the wireless-n drivers release by netgear…my question is this…which method would both provide me the ability to have BOTH cards available AND give me the best wireless-n speeds?

If I have to choose, I choose to have the wireless-n card working at it’s full 270mbps speed even if I have to disable the first card as I have a matching netgear router to connect it to.

Thanks for any comments.
