Question about "wireless N disabled" models

[atekant]

I am looking at a model of T61p that I like, but it is one of the "N disabled" models.

What is exactly involved in plugging in an Atheros card in these?
Is the N antenna present, so it is a matter of just replacing the wifi card? Or will I have to also buy an antenna assembly, wire it into the display and all that stuff. I found an FRU (42T0865) that I assume is an N upgrade kit, but the parts people said it is $200, which makes me think it is more than just a card.

Also, if it involves antennas, wiring, etc., does that break the warranty?

I am in Canada, so I can't order customized until October for some reason.

Thanks

Not sure if you ever got a reply to this... The Intel 4965AGN card is very expensive so that price may be the real one... It is still not being sold separately by Lenovo, and only the ones you buy from Lenovo will work in the T6x machines. Standard Intel WiFi 4965AGN cards will not work (get an 1802 error). I believe that most T61p models had the 3rd antenna, but am not positive.
