Hmmm, thats a tricky one John. This is an excerpt from the documentation for
the feature: "Do not configure ports that belong to a PAgP or LACP
EtherChannel as private VLAN ports. While a port is part of the private VLAN
configuration, any EtherChannel configuration for it is inactive."

http://www.cisco.com/en/US/docs/switches/lan/catalyst3560/software/release/1
2.2_44_se/configuration/guide/swpvlan.html

I think its a tricky one. Some releases for the Cat6Ks dont actually support
pVLANs. What IOS are you running?

Anyway, what about L2/MAC ACLs? VACLs? Those are some options that you have
anyway...

HTH a little.
