Your PA-GE should work just fine.. Are you using subinterfaces, or trying
to apply the 'encapsulation' command to the main interface? The former
should work; the latter will fail.

To route between VLAN 15 and 16, for instance:

    interface GigabitEthernet0/0/0
     no ip address
    !
    interface GigabitEthernet0/0/0.15
     encapsulation dot1Q 15
     ip address 10.15.0.1 255.255.255.0
    !
    interface GigabitEthernet0/0/0.16
     encapsulation dot1Q 16
     ip address 10.16.0.1 255.255.255.0

The config above was from 12.0(4)T...
