Hmm, I think the question was about modifying the driver..
At any rate, the story seems to be like this..
If you did not read and understand the kernel / driver sources enough to
know what you are doing when modifying them, then it is advisable to not
even try.. Both provide documented ways to be extended, and if possible,
those should be used..

Having said that, I have made my own modifications to the driver (related
to the [] operator, which works in a way that I disagree with... :)

The DGD driver sources are quite readable and I had little trouble finding
the things I needed. That said, it is also amazingly easy to introduce
very subtle bugs when not understanding fully what you are doing in there.
