I tried hacking with R300 a little bit, so here are the results:

     1. R300 microcode loads well (I am using Mobility M10)

     2. The server starts up fine and displays "direct rendering enabled"
        along the appropriate messages in XFree86.0.log

     3. glxgears displays black windows and produces 100% CPU load
        kill -TERM does not work, kill -KILL hangs the machine.

Questions:
     1. Am I correct to assume that since direct rendering was enabled
        the X was using CP accel funcs which then proves that CP is
        working correctly ?

     2. It appears that Mesa driver needs adjustment. Should I try to
        #ifdef existing r200 driver or start a new directory ?

     3. I would appreciate points on how to turn on/off various
        functionality in Mesa driver.

        For example, can I modify the pipeline struct to turn on/off
        various processing stages ?

                  thank you !
