I would say it is supported. Even the documentation has an example where one port of the group is 100GE and two others are 10GE:

Also with MPC7 its not like its honor based to only use 240G per PFE ... its a hard limit ;)

If you run in PIC Mode with 100GE set, than in deed the other ports are disabled:
"For example, if you choose to configure PIC 0 at 100-Gbps speed, only ports 2 and 5 of PIC 0 operate at 100-Gbps speed, while the other ports of the PIC are disabled."

I mean what else should it do, there are only two 100GE Ports per PFE anyway ;)
