If you are really interested the first place to help is getting the
new Xegl Xserver working. It is discussed on the xorg, dri-devel and
dri-egl mailing lists at freedesktop.org.

We probably won't start working on the other console pieces until the
Xserver is ready. Without the Xserver it is hard to do anything in the
new environment.
