Comment # 42 on bug 1118689 from Andreas Stenglein

I uninstalled gfxboot and the problem persists.
However I use grub2 that already contains framebuffer/graphics console.

In /etc/default/grub I changed the line
GRUB_GFXMODE=auto
to some configurations and run 
grub2-mkconfig -o /boot/grub2/grub.cfg
and rebooted the machine.
(one could change the setting using YAST also)

640x480 -> works
800x600x24 -> works
1024x768x16 -> as far as I remember it bootet once, than 3x lockup
1280x1024x8 -> works
1280x1024x16 -> lockup
auto -> lockup (1280x1024x32 gets chosen as shown by grub console)
