I have created a Gentoo Linux for the new Creator board. If anyone is interested check out my web site
I will have an image ready in a week or two.
So far I have a working gentoo with the kernel 3.18.3, I am waiting for imagination to release code for the GPU for the OpenGL, basically same situation that Debian is into.
My gentoo has gcc 5.2.0 installed with librairies updated for it.
What is left to do to get my image ready is the graphic interface. I am working on getting mate desktop 1.10 working.
Your km driver and user mode binaries already work on other distors. We need only change RPATH of um binaries from /usr/local/XSGX/lib to the normal place /usr/lib. (or probably remove RPATH value from binaries)
