First, lets be clear on what version of SuSE that you have, 9.0, 9.1, 9.2 or 9.3?
Secondly, realize that if you have SuSE 9.0, this is a very old version and instructions for this particular version will be hard to come by.
What version Belkin F5D7050 is this? It makes a difference, as there are 4 or more versions (according to the Belkin site) which have various chipsets that run the card.
You can use the package ndiswrapper to run your native Windows drivers (possibly) if you have the drivers cd.
To show an example, see
this SuSE article for an example of the Ralink chipset version.
You will probably have much better luck with a newer version of SuSE, such as version 10.1. 10.2 or 10.3.
