* Defines for the used register addresses (mw)
*
* NOTE: There are some registers that have different addresses when
* in mono or color mode. We only support color mode, and thus
* some addresses won't work in mono-mode!
*
* General and VGA-registers taken from retina driver. Fixed a few
* bugs in it. (SR and GR read address is Port + 1, NOT Port)
