[mrtg] Graphing Gigabit Interfaces

Hey all, I'm trying to graph some gigabit interfaces on my cisco 6506 
8-port gigabit blade and the graphs are maxing out at about 97 Megs.

I noticed that I needed to use SNMPv2, but this hasn't seemed to alleviate 
the problem, as things still get set thusly:

### Interface 10 >> Descr: 'GigabitEthernet3/8' | Name: 'Gi3/8' | Ip: 
'219.128.66.73' | Eth: '' ###

Target[78.4.110.254_10]: 10:h0stm3 at 78.4.110.254:::::2
SetEnv[78.4.110.254_10]: MRTG_INT_IP="219.126.66.73" 
MRTG_INT_DESCR="GigabitEthernet3/8"
MaxBytes[78.4.110.254_10]: 125000000

^^^ The above looks right, as in it's 10X any fast ethernet interface 
(which mrtg gives FIVE zeroes) -- but it's still 125 million bits, which 
is 125 megs, right?

Title[78.4.110.254_10]: Traffic Analysis for 10 -- ads-bsh-cr01
PageTop[78.4.110.254_10]: <H1>Traffic Analysis for 10 -- ads-bsh-cr01</H1>
  <TABLE>
    <TR><TD>System:</TD>     <TD>ads-bsh-cr01 in </TD></TR>
    <TR><TD>Maintainer:</TD> <TD></TD></TR>
    <TR><TD>Description:</TD><TD>GigabitEthernet3/8 Uplink to Arbinet 
(AS18775) via han-bsh-cs05-g0-2 </TD></TR>
    <TR><TD>ifType:</TD>     <TD>ethernetCsmacd (6)</TD></TR>
    <TR><TD>ifName:</TD>     <TD>Gi3/8</TD></TR>
    <TR><TD>Max Speed:</TD>  <TD>125.0 MBytes/s</TD></TR>

^^^ And no matter what I do, this doesn't get fixed either.

    <TR><TD>Ip:</TD>         <TD>218.126.66.73 ()</TD></TR>
  </TABLE>

If someone would like to test with me, let me know and I'll be more than 
willing to work with you.  (these ips have been munged).
