[c-nsp] 6509 ACE/FWSM Modules??????????

[James Slepicka]

Should work fine (though, admittedly, I haven't deployed this config).  
The purpose of PAgP+ is to provide dual-active detection should the VSL 
between your VSS pair fail.  If your devices don't support PAgP+, you 
need to configure a dedicated link to perform this detection instead.
