Radeon was originally a document written driver, in fact most of radeon was written with docs from ATI or patches from ATI. Most of the reverse engineering was in the 3D driver in Mesa not so much in the 2D X.org driver. RadeonHD was a clean driver for r500 and above however the developers took what the radeon driver maintainers (i.e. me and an AMD employee) believed to be an unsupportable direction in terms of ignoring the ATI bios bytecode for setting up the hardware. So radeon just added support for the bytecode interpreter and worked on lots of hardware. RadeonHD has since switched to using this interpreter on nearly all hardware, but at that point it was too late to rescue it. Novell/AMD attempted to prop up radeonhd for political reasons, but it seems to be losing the battle now. So radeonhd is going nowhere new, radeon is the only driver that supports the new kernel modesetting systems. With kernel modesetting the X.org 2D driver doesn't do very much anymore, and everything that is left for it to do is shared code between the two drivers.
