Apologies for bumping the post.... My notes show the following:
WS-X6148A-GE-TX *Number of ports: 48 Number of port groups: 6 Port ranges per port group: 1-8, 9-16, 17-24, 25-32, 33-40, 41-48 *The aggregate bandwidth of each port group is 1 Gbps. WS-X6148-GE-TX *Number of ports: 48 Number of port groups: 2 Port ranges per port group: 1-24, 25-48 Note WS-X6148-GE-TX, WS-X6148V-GE-TX, and WS-X6148-GE-45AF do not support these features: *More than 1 Gbps of traffic per EtherChannel Sorry, I was thinking 6148A and the OP has specified the non-A version hence the confusion on my part...

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.
