It should like the Atheros 5212 as IBM re-sold this a/b/g card for some time as the "IBM a/b/g" card. I can believe that other Atheros cards will fail, but that one, if you can find one, should work fine. It does on my ThinkPad T43, thought the BIOS on yours may be a bit too old. (You might want to look for BIOS updates that might support it.) ath0@pci0:11:2:0: class=0x020000 card=0x057e1014 chip=0x1014168c rev=0x01 hdr=0x00 -- R.
