That card has been problematic in Linux as well as FreeBSD. Sam Leffler recently came out with something that now enables it work in 64 bit with Linux.
Additionally, the build that you mention, the 2756 stopped working with some later Linux kernels--Sam's newest fixed that too.
If anyone needs to get that one going on Linux, as me. I would actually try the later version of the HAL, from that very latest patched snapshot (around post 220 or so in that ticket 1679.
(Latest snapshot, with 64 bit and later Linux kernel support is at
http://snapshots.madwifi.org/special...0080604.tar.gz)
If anyone has the ASUS give it a try and see if it works. The 2566 one is from last November.
Lastly, if anyone is trying to get that card working with Linux (not FreeBSD)
