In 9.2 - yes. Each card has a MAC address. Since that is now part of the
name in 9.2 (not sure about 9.1 - anyone on the list know 9.1?), your
problem has a solution.

In /etc/sysconfig/network, the config files are not named 'ifcfg-eth0'
and the like. Mine is named ifcfg-eth-id-00:06:5b:a6:e5:9d, which tells
me exactly which card it is. This will never change because of slot or
driver load order changes. In YAST, the MAC address is provided so you
know which you are configuring.

I think this is all part of the 'udev' system that SUSE now support. In
this system, you can control the names of all devices based on many
different properties. Not sure what the long-term system variances this
will bring about will do, but the idea has some nice uses here.

If you do not see this in 9.1, then I guess it is a new thing for 9.2
