Have you tried searching for Infinipath drivers at the SUSE 10.3
repositories?  If you're using OpenSUSE rather than SLED / SLES,
perhaps it would be worth checking the community build repository too.
 Maybe someone has already done the build work for you.  I'm
continually amazed at the useful stuff I find there that I was certain
I'd have to build for myself.

For that matter, a clean install may be in order as a last resort.

Good luck!
