wheel mouse

Wheel Mouse trouble with Suse Linux 9.2 (SaX2, xorg.conf, explorerps/2, ZAxisMapping)

I wanted to activate the wheen of my USB mouse, but everytime I went to Yast2 > Hardware > Mouse the X server crashed and threw me into a text console. Also using SaX2 didn't work (there is a button under Input devices > Properties > Activate mouse wheel). Funnily the wheel usind to work in 9.1.
