freebsd stable - Jul 2006 - SNMP access to pf ALTQ data?

Forgive the cross-posting, but I think I need a wider audience.

Is it possible to track pf ALTQ usage with MRTG? I notice that FreeBSD's 
built-in bsnmpd has a module and mibs to support pf, but I know too 
little about SNMP to figure out how to access the queue stats.

Specifically, I'm looking to make a series of MRTG graphs that show the 
total bytes that pass through each queue. I figure if worst comes to 
worst, I can work out a separate program that parses the output of 
'pfctl -vsq' and returns that as MRTG-readable input, but it would be 
much smoother to get it via SNMP, if it can be done.

Any help would be appreciated. I'm sure others would be interested in 
this as well.

I got one of those, a small python script which feeds the data into a  
rrd file:

https://svn.stromnet.org/repos/misc/trunk/rrd/pfque-rrd.py

Works fine, the only problem I have is when i reload my rules (that  
is, reset the counters).. The graph goes mad ;)
Altough, if there is some way to do this via SNMP instead, I would  
also like to know...
The above scripts uses tftp to move the rrdfiles to my graphing host.  
I call it from crontab every minute.
For the graphing I use this:

https://svn.stromnet.org/repos/misc/trunk/rrd/pfque-graph.py

And the result looks like this:

http://stats.stromnet.org/router/details.php?file=pfqueue_out

If you look at the last month/year graphs, you see the problem with  
resetting the counters..
