Before I start to implement the good suggestions, I'd like
to know how such a merge would look like in your opinion.

Over the long term, I see the old driver vanishing, as it is too
complicated to use (you need to be a video and SMI register
expert). It is not much more than a jump into the board specific
setup routines. However, removing the old driver would break half
a dozen  of boards (inacceptable).

BTW the driver will probably also work with the new SM107,
which as no USB, Keyboard and all this stuff.
