First, make sure that devices are not being automatically started by system at startup or hot-plug.
Go in with Yast and make sure eth0 and eth1 are configured to start manually.
Then use a script to setup the bridge (as per above).

I haven't looked at what sort of initialization Suse does for bridges through Yast,
because every distro is different.

When you say it doesn't work, what do you mean, system crashes? packets aren't bridged? devices aren't up?

What you should look at is the output of brctl status commands.
Best to wait till after the initial learning period and do:
 brctl show br0
 brctl showstp br0
 brctl showmacs br0
