wireless pci card

[arden]

hi all 

I'm making some changes to my home network and my BSD 5.2.1 box is going
to act as a gateway/firewall I would like to add a wireless card to give
my Linux laptop access to the net in any room.

Dose anyone have any recommendations as to which cards are supported?
also are they supported out of the box or will i need to do any kernel 
tweaking?

Thanks in advance
