Since I didn't find this issue solved anywhere on the internet nor on these forums, I'm posting it here.
How on earth are you supposed to get these crappy ATI-drivers installed on SuSe 9.2 Professional?? I assume Xorg is causing lots of the installation trouble.
I did manage to install them on SuSe 9.1 with some info from the internet. But I get absolutely no success with 9.2.
BTW, nVidia's drivers installed with one click from YasT. Way to go, nVidia!
