This is not the end of reverse engineering for radeons

The vertex instruction format was an oversight.  I'm already working on getting that
information out.   We didn't have an official R5xx 3D programming guide, so I put this one
together from a variety of internal sources.  There may be things I've missed and we will
release updated information when needed.  Plus, the document isn't the end all and be all, if
you need more information on anything, just ask!  In most cases we can get the information
released.
