[mrtg] 64-bit counters with SNMPv1?

I have a device (a Nortel OM3500) which has high-speed interfaces.  So,
I need to retrieve traffic counts using ifHCInOctets, etc....i.e.,
64-bit counters.   It appears to me that MRTG uses the 64-bit counters
when SNMPv2 is used.  However, in this case, v2 is apparently not
supported.  To verify this, I entered the following commands:

snmpget -c commstr -v 2c xx.xx.xx.xx
(response: Timeout: No Response from xx.xx.xx.xx)

snmpget -c commstr -v 1 xx.xx.xx.xx
(response: IF-MIB::ifHCInOctets.17 = Counter64: 6058121224)

This suggests to me that the box does not support SNMPv2.  Is there a
way for me to make use of the 64-bit  counters, while using SNMPv1?  (Or
if someone knows of a way to enable SNMPv2 on a Nortel OM3500, that
would also be a quite acceptable - perhaps preferable -  solution.)

Any help would be greatly appreciated.
