I have two BCM4322 soldered on a board of a router (Linksys WRT610N V1)
and connected via PCI to the main Chip (BCM4705/BCM4785). My BCM4322 has
a ARM Cortex M3 core, a USB host core, a PCI and a PCIe core in addition
to the "normal cores". My BCM4322 is running as a softmac device and is
supported by b43 and ssb, 2.4 Ghz wifi is working.

This chip is probably capable of running in softmac mode on a PCI or
PCIe card or in fullmac mode in a USB dongle, at least that's my
explanation for the ARM core on this device.
