no, all the hardware that is commented should work just fine. I tested this driver
on 82571, 82573 and ich8/ich9 - extensively.

the reason that we disable them is that we're going to migrate devices over in
batches. At introduction we'll support ich9, afterwards we'll drop in the IDs of
the other groups of silicon.

if it's a fix, yes.
