Thanks for the diver link. - will see what it does.
I cant recomend firmware upgraded or non-apple cards...
... to coin a phrase from a well known manufacturer: - 'can yield unexpected results'
(never thought I'd ever say that!...)
While it may work fine for you - there are other users that shouldn't take the risk.
As mentioned: the GT120 card is a good cheap fix for the moment until apple releases an update
