I noticed that without software version 3.500 things didn't work quite
right. Furthermore, that is the minimum required software version to
allow the LACP ports to be 'tagged'.

My config from a 12GCF to a Cisco 3560 looks like this, and works good:

Cisco 3560:
interface GigabitEthernet0/49
 switchport trunk encapsulation dot1q
 switchport trunk allowed vlan xxx
 switchport mode trunk
 channel-group 1 mode active
!
interface GigabitEthernet0/50
 switchport trunk encapsulation dot1q
 switchport trunk allowed vlan xxx
 switchport mode trunk
 channel-group 1 mode active

interface Port-channel1
 switchport trunk encapsulation dot1q
 switchport trunk allowed vlan xxx
 switchport mode trunk


Foundry:
interface ethernet 5
 link-aggregate active
!
interface ethernet 6
 link-aggregate active
