Expanding xorg with kaa is perpetuating some of the big flaws in the X
server. Xgl pushes all of the PCI probing and manipulation of hardware
registers down into device drivers when synchronization is controlled
by the kernel. kaa continues with the current X server which does evil
things like manipulate the PCI bus from user space. It also turns off
other video cards that it doesn't have drivers loaded for even though
those cards may be in use by other apps. A big goal of Xgl is to
remove the need for the server to run as root. Removing root makes it
hard for the X server to do nasty things. Long run the Xgl model
should have superior performance to kaa since Xgl exposes full OpenGL
including shaders.

If you have the skills to work on kaa why not consider helping with
the new memory manager in the radeon driver.
