	Yup, function not supported. Another hack available to you should
other suggestions like the mii package fail, is simply recrimp your
ethernet cable, using only pairs 1-2, 3-6, as per the 10baseT cabling
spec. This has it's caveats as well, since there are two 100baseT cabling
specs, T4 and T8, one of which used only two pairs (T4) in the same manner
10baseT does. I'd save this for last ditch efforts. =)
