Well, I do not have a draft N router.
However, on Fedora (and perhaps on all Linuxes) I have not seen
any util that will put the wifi card in mode G or N or A.
I check iwconfig, and I did not see anything relevant to draft N.
I looked at wpa_suppicant, and did not find anything there either.
I think it is automatic.
So, if your access point (router) is draft N, the card itself will detect
draft N protocol, and connect in that mode.
So, I do not believe it is a driver issue, but I could be wrong.
if you have rt2860 based wifi, all you have to do is try latest
stable vanilla kernel from http://www.kernel.org/.
You have nothing to lose except a little bit of time.
