Given my past experience, I created the following:
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:25:90:ab:ab:1f", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1" SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:25:90:ab:ab:1e", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
Dumb question, but have you tried reversing the order? (Define eth0 before you try to define eth1.)
