[mrtg] polling ATM sub-interfaces on cisco 6509

I would like to know how to poll for the ATM sub-interfaces on cisco 6509.
I have a cisco 6509 going ballistic when polling for the ATM
sub-interfaces. The device reports that it receives thousands of polls
for one pair of mib objects, though I doubt mrtg is actually sending all
these polls. This only happens for the ATM sub-interfaces, all other devices are fine.
Mrtg (cfgmaker) has flagged it as an snmp v1 interface. If I modify the
config to use snmp v2 the problem goes away.
The cfgmaker script probe for 'ifHCInOctets' fails, therefore mrtg flags
this as snmp v1. Here is a snippet;
--base: snmpget [device]::2:1::2:v4only for ifHighSpeed.86 -> 150 Mb/s
--base: snmpget [device]::2:1::2:v4only for ifHCInOctets.86 ->
--base: check for HighspeedCounters failed ... Dropping back to V1
Are there any particular cfgmaker flags to use for ATM sub-interfaces?
Does mrtg 'really" send all these snmp v1 polls on an atmsubif?
Some device details;
SNMPv2-MIB::sysDescr.0 = STRING: Cisco Internetwork Operating System
IOS (tm) s72033_rp Software (s72033_rp-PSV-M), Version 12.2(18)SXD,
RELEASE SOFTWARE (fc2)
Some interface details;
IF-MIB::ifType.86 = INTEGER: atmSubInterface(134)
IF-MIB::ifDescr.86 = STRING: ATM9/1/0.74-atm subif
IF-MIB::ifName.86 = STRING: AT9/1/0.74
IF-MIB::ifSpeed.86 = Gauge32: 149760000
any thoughts appreciated.
