Sorry, I wasn't aware of that. With iSCSI these cards definitely help,
but it there's no stack used for the AOE stuff then cool. Am I right in
thinking then, that most of the increase in load is interupt load for
I/O on the adapter?

As I understand, this is the whole point of ATA over Ethernet (vs
iSCSI): it doesn't actually use TCP/IP, it runs on raw ethernet (and
thus isn't routeable but that's probably more of a feature than a bug).
