Do you have 71-biosdevname.rules in either /etc/udev/rules.d or 
/usr/lib/udev/rules.d ? I expect that would run after the persistant 
name rule and reset things.

I actually have the opposite issue in that I want to use the biosdevname 
names, since eth0 and eth1 have been getting assigned randomnly for a 
while now on one of my machines and the renaming ability of the network 
initscripts seems to have gone away.
