Prism54 Chipsets Supported?

Hi,

I am currently using a Dell TrueMobile 1300 (Broadcom) on my Dell 
Latitude D600 Notebook. Thanks to Bill Pauls awesome work it is performs 
very well for daily und "normal" wireless lan usage.

But i want to run some tools, that are only available fo wi-cards.
Is Prism54-Chipset already supported? I read something that a driver for 
linux exists on www.prism54.org. will it make it to freebsd or is it 
highly unlikely?

Some on the lists posted, that he has replaced his card with an 
ath-based one. Maybe ath is an alternative to wi, but i'd relly prefer 
wi (802.11g or a is a must have).

thanks

Patrick
