hm, this seems to have popped up in the last few days, never had it 
before:

  sysfs: duplicate filename 'eth0' can not be created
  WARNING: at fs/sysfs/dir.c:424 sysfs_add_one()

   net eth0: device_rename: sysfs_create_symlink failed (-17)

32-bit bzImage kernel - config attached. (The 64-bit kernel even lost 
connectivity due to this and ifcfg-eth0 got renamed to ifcfg-eth0.bak by 
kudzu.)

detected order of the interfaces is:

  forcedeth 0000:00:0a.0: ifname eth0, PHY OUI 0x5043 @1
  eth1: RealTek RTL8139 at 0xffffc200001f2000

and that's the ordering in /etc/sysconfig/network-scripts as well.
