Moving the lenovo drivers and especially removing the duplicate
functionality sounds good to me.

I have a few small remarks below, other then that this looks good
to me.

No special protocol for moving files.

The moving should definitely be safe. For the refactoring planned on top
would be good if you can test on some actual hw.
