See Warris' recent post to C-NSP which linked to documentation about
the load balancing behaviour of MPLS labelled traffic for the
ME3600X/ME3800X and ASR920 boxes, they are two examples of Cisco
devices which look into the pseudowire.

They also detect if there is or isn't a control-word.

For stuff like the 7600 is more basic:

"MPLS Layer 2 VPN Load Balancing: Load balancing is based on the VC
label in the MPLS core if the first nibble of the MAC address in the
customer Ethernet frame is not 4."

Cheers,
James.
