LabVIEW does not directly require VISA as a dependency. Or GPIB for that matter. They are included on the CD as a convenience when installing since they are common drivers. Do you need them installed? If so, you might also look for the latets versions of those drivers on the web. They will have updated components for newer kernels. Also read the README for VISA. It has the steps you need on openSUSE to make the modules and prepare them.
If you got to the VISA installer, then that means that LabVIEW itself is already fully installed. If that is all you need then you are done.
