Something along the lines of :
if there is an an existing deleted interface with the same ifName, grab its port_id
Though, this wouldn't work when two interfaces are flipped (happens a lot on linux reboots).
Possibly at poll time we could compare ifName and grab a different port_id even if the port isn't deleted?
Possibly a per-OS whitelist to enable the functionality would work, but checking this stuff at every poll might prove... fragile.

But the RRD is numbered after the ifIndex...
Sounds like all of the solutions are bound to be icky. I personally think that in order to do it in a non-fragile manner it would be necessary to look at the time range of data in the RRD, which is probably too intensive to do in the poller.
