Fixed this issue now. Should fix this issue for TW and Leap.

- Unfortunately removing no longer used kernel modules via 
  %triggerpostun doesn't work since kernel updates are not
  considered "atomar" when using YaST/zypper (only safe when
  using rpm) [boo#1182666, boo#1164520]

I hope there will be still a driver update this week.
