this is basically how linux does OOP :)
the lowest level driver instantiates the object, but sets it with
helper/library functions ("methods" in OOP speak) from the higher
layers.
It gives a really clean model in the light of a world where
"hardware does weird shit" which can't be "nicely" mapped in traditional
OOP paradigms, but works quite well in this linux model.
