The error about GfxMenu should only appear in the first logs which I made before the fix was out. The latest logfiles are produced using the updated yast2-firstboot. For the full /var/log/YaST2 folder I am afraid you will have to wait till next weekend. You could ofc. always try to reproduce it on an arm board (e.g. raspberrypi, beagleboard) if one is available.
