For USB, you will almost for sure have to use the NDIS wrapper driver. I 
have not tried it, been shying away from it for at least a year now. I 
believe it is built into FC11, so will be part of Centos 6 at some date 
off in the future ;)

PCMCIA or miniPCI is more promising. You can use the DKMS driver (?) for 
say madwifi, and be quite satisfied with the results.

You say that the current wifi is 'builtin'. Is that on the board or a 
miniPCI? If the later, pull it out and put in something supported.
