I've not used SuSE in years....but here are a few things you might try.
***Disclaimer***
I'm new to wireless on linux too....so this may not work
First, my distro uses wlan0 for the wireless card. So you might try bringing wlan0 up instead of eth1.
Second, even with wlan0 down, iwconfig still finds my router and shows the SSID. So....is your router set to broadcast it's SSID?
Also, from what I've read online, it looks like SuSE may use either wlan0, eth1, or wifi0.
If you're not using encryption, try the following:
ifconfig <network_interface> <local IP address> netmask 255.255.255.0
If it succeeds in assigning a static IP to the interface, you should see it in the list when you run ifconfig.
Since we haven't specified a default gateway yet, you won't have internet access, but you should at least be able to ping your router.
If you can ping the router, at least you know it's not a problem with the card or the driver.
