This chip works (though not quite "supported", that is, can't guarantee that it will work for you, and speed is not up to par with wl_hybrid) in wireless-testing. It should also work in compat-wireless, though compat-wireless is having problems with 64-bit DMA lately (probably also affects the G-PHY 4311/02). Specifically, the Dell 1397 (half-mini version of the 1395) and the HP 459263-002 are known to work.

Need I backport some code from wireless-testing?
