CPU statistics for VIP cards are supported via SNMP, however
it is not a trivial task to map the indexes to the actual
VIP cards.

But here is how I do it:

Get a list of the CPU physical indexes from the CISCO-PROCESS-MIB

snmpwalk -v 2c -c $COMM $HOSTNAME 1.3.6.1.4.1.9.9.109.1.1.1.1.2
SNMPv2-SMI::enterprises.9.9.109.1.1.1.1.2.1 = INTEGER: 9
SNMPv2-SMI::enterprises.9.9.109.1.1.1.1.2.2 = INTEGER: 16
SNMPv2-SMI::enterprises.9.9.109.1.1.1.1.2.4 = INTEGER: 28
SNMPv2-SMI::enterprises.9.9.109.1.1.1.1.2.5 = INTEGER: 31
SNMPv2-SMI::enterprises.9.9.109.1.1.1.1.2.6 = INTEGER: 19
SNMPv2-SMI::enterprises.9.9.109.1.1.1.1.2.7 = INTEGER: 22
SNMPv2-SMI::enterprises.9.9.109.1.1.1.1.2.8 = INTEGER: 25

This maps the CPU index to the entPhysicalIndex which you can
then interegate to find out what type of CPU it is, and which
slot it is in.

The entity name OID is 1.3.6.1.2.1.47.1.1.1.1.7.X and
the entity description OID is 1.3.6.1.2.1.47.1.1.1.1.3.X

where X is the INTEGER value returned for each CPU.

By looking at the entity name:
  snmpget -v 2c -c $COMM $HOST 1.3.6.1.2.1.47.1.1.1.1.7.16
  SNMPv2-SMI::mib-2.47.1.1.1.1.7.16 = STRING: "Line Card 0"
we determine that we have a Line Card in slot 0

By looking at the entity description:
  snmpget -v 2c -c $COMM $HOST 1.3.6.1.2.1.47.1.1.1.1.3.16
  SNMPv2-SMI::mib-2.47.1.1.1.1.3.16 = OID: SNMPv2-SMI::enterprises.9.12.3.1.9.7.26
we get another MIB value that requries some translation against the CISCO-ENTITY-VENDORTYPE-OID-MIB

I use the following command to make sense of this:
  snmptranslate -Ov -mCISCO-ENTITY-VENDORTYPE-OID-MIB SNMPv2-SMI::enterprises.9.12.3.1.9.7.26
  CISCO-ENTITY-VENDORTYPE-OID-MIB::cevC7xxxVIP250
which shows that it is a 7XXX series VIP250

And there you go, you now know that :

1.3.6.1.4.1.9.9.109.1.1.1.1.4.16 is the 1 min CPU value for the VIP250 in that is in Slot 0 and
1.3.6.1.4.1.9.9.109.1.1.1.1.5.16 is the 5 min CPU value for the VIP250 in that is in Slot 0

As most are probably aware, the CPU indexes are assigned in a random manner, and can often
be renumbered when problems like a VIP card crash and/or restart are encountered.  It is worth
scripting the above process to rebuild the configs on a regular basis.

Hope this helps.
