Axel Dörfler cbd4081064 * Fixed PLL timing computation for the i9xx chips - I mixed post2 min/max values, and did
not take the VCO limits into account; both could (and would during testing) create invalid
  frequencies.
* Also reverted the order in which the PLL divisors are traversed to match the order of what
  is used in the X driver to create comparable output (our error computation is based on float,
  though, and should therefore create more accurate values).
* The i965 introduced a special register for the surface; the former display base register
  is now only used for the view offset. Instead of setting the base manually here and there,
  there is now a set_frame_buffer_base() function.
* The DPMS code will now also turn off/on the PLL clock generator.
* The code needs some more cleanup, and while the driver now produces the correct timing on
  my i965 system, I'm now greeted by a black screen after startup.
