Ok, I added all that information to the bug.

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?

Best regards,
