  22  * Based on Permedia 3 driver by Måns Rullgård
  23  * Thanks to Gilles Frattini for bugfixes.
  24  *
  25  * Changes:
  26  *   18/01/03
  27  *     MMIO is no longer used, sidestepping cache issues on EPIA-800
  28  *     TV-Out modes are now better supported - this should be the end
  29  *       of the magenta stripes :)
  30  *     Brightness/Contrast controls disabled for the time being - they were
  31  *       seriously degrading picture quality, especially with TV-Out.
  32  *
  33  * To Do:
  34  *   Implement Hue/Saturation controls
  35  *   Support / Test multiple frames
  36  *   Test colour-key code more extensively
