Broadcom wireless drivers

Hi, 

I have done the basic test you suggested on my laptop (a Macbook Air mid 2011). 
See 
https://wiki.freebsd.org/Laptops/Apple_MacBookAir4%2C2?highlight=%28%5CbCategoryLaptop%5Cb%29
for more on this.
I decided to make more tests and to install FreeBSD 11-CURRENT on the Mac. It worked well using rEFInd. FreeBSD 11-CURRENT 
runs now besides my Mac OSX Mavericks. The problem seems to be the wireless support at the moment because Apple uses Broadcom and that seems, if I am not mistaken, not to be too well supported at the moment in FreeBSD. Has there been work done/any progress on this recently?
If not,  is there at least a theoretical solution for this. I volunteer for testing and what ever :).
