I'm not familiar with the Atheros firmware, but the likely answer is no. 
Linux virtualization (probably better described as emulation) is at the 
user space level, i.e. it mimics the interface of Linux syscalls. Device 
drivers work in kernel space, and the FreeBSD kernel has very different 
internals from Linux.
