What if you created a startup script that used mii-tool to force the
speed/duplex of each interface? E.g.:
/sbin/mii-tool -F 100baseTx-FD eth0 # 100 Mbps/full duplex
/sbin/mii-tool -F 100baseTx-HD eth1 # 100 Mbps/half duplex
/sbin/mii-tool -F 10baseT-FD eth2 # 10 Mbps/full duplex
/sbin/mii-tool -F 10baseT-HD eth3 # 10 Mbps/half duplex
I haven't tested this because I don't have a machine with multiple NICs of
the same type in front of me, but it seems like it should work.

Probably. I thought maybe ifcfg-eth0, but I don't see anything about link
speed or duplex setting in there.
