Etherchannels are a little pointless on the WS-X6148-GE card and similiar. They have 1GB/s ASICs, so you'll never exceed 1GB/s anyhow. And the ASIC to physical port ratio also limits you. But generally speaking, cross module etherchannels are a good idea and AFAIK is recommended from Cisco for high availability.
