The guessed register name is from me. On the R300, fglrx almost always writes 0 to this register before changing any vertex processor-related state, so I assume that it has some kind of serialising purpose. However, I have yet to run into any situation where emitting it makes any difference in my own code, so I don't know this for sure. cu, Nicolai
