OK, everything is basically fine, then.  Your card is auto-negotiating
full-duplex 100 mbps, which is what you want.

Whatever MRTG thinks it is, that's what it will display it as. It will
basically believe whatever it's told; if the card tells it "I'm ethernet"
it will graph it as such.  If you tell it "The card lies; it's fast ether"
then it will graph it as such.  So I mean having MRTG think it's a 100
(which it is) and mean it.

Yes, it is.  Take a look at the cfgmaker code (perl).  I don't think you
have a problem with snmpd, since you are getting SNMP information.  Since
the card type information does not match the actual link speed, but your
other numbers are correct, that means the card is reporting itself as a
plain ethernet card regardless of whether it's in Fast Ether mode or not. 
It's not smart enough to say "Hey, I'm at 100 mbps, I should report myself
as type 62."
