@Hans "work" is a relative term here. They are all recognized and started.
Going into details would go beyond the scope of this thread, I think.
dmesg excerpt:

I am only *using* the accelerometer, so a mask of "1" or "0x1" respectively
would suffice.

Testing the other sensors is non-trivial. I branched my refactored version of
the driver to extend it with an API to allow for reverse-engineering the PCI
device to detect other sensors. But again, this maybe something to discuss in
another place (or write a paper about :p).
