Some switches (I'm sure the Cisco ones, for example) will happily do
etherchannel packet distribution based on IP header info even if
they're just configured to switch and not route.

All it has to "know" about IP is which offsets in the packet
correspond to what it should be hashing against. And (cisco) switches
have been blurring the L2/L3 switch boundary for a while (think IGMP
snooping for a very early example.)
