I will try to be kind in my reply as well ;-)

For the 3.2 kernel the brcmfmac only supported SDIO devices. USB support
was added in 3.4 kernel. However, the Linksys AE1200 needs a different
driver model that is not supported. So the only option for x86 is using
ndiswrapper.

So the answer is no for the two reasons above. The brcmfmac support
BCM43235 only for chip revision 3 and higher. The Linksys AE1200 has an
older revision that requires a driver model that is not supported.

The brcmfmac driver is already working for ARM platforms. We have both
SDIO and USB running on Pandaboard platform.
