Have you seen

http://lists.freedesktop.org/archives/dri-devel/2012-May/023536.html

and

http://lists.freedesktop.org/archives/dri-devel/2012-May/023544.html

The first patch is a generic gem helper for dma_alloc_* backed memory
which could serve as a drop in replacement for your gem code. The
latter is a generic helper for the framebuffer handling on these
devices. I saw that your driver supports planes which Lars' patch
currently doesn't, but it should be easy to add support for this.

I hope these are useful, if not, could you tell what's missing?

Sascha
