Actually I booted an older Kernel (3.7.10, openSUSE 12.3 kernel) which has both drivers configured as modules. The interesting thing is: I was not able to load acpiphp there, it errored out with ENODEV. So maybe something changed, making acpiphp more (too?) relaxed. Should I try building the latest kernel with both drivers as modules to see if this makes a difference?
