Dear Marco,

This depends on the implementation. Often you will find  some  device
driver  provided  by  the  chip  manufacturer  (or  some  other third
parties). And often this driver will provide a  standard  framebuffer

It might have one after adding the driver to your kernel source tree :-)

Parameters are passed in registers plus some data structure  in  RAM.
How  and  where  Linux stores this information depends on a couple of
things, like processor architecture and kernel version.

Why do you ask?

[Maybe we should move this discussion into a Linux group?]
