  - Add new functionalities and modify static functionality table 
  - Performance : 16 bits IO

v0.4
  - Implement the remaining functions :
	- chargen ax=1100, ax=1101, ax=1102, ax=1103, ax=1104, ax=1110,
	  ax=1111, ax=1112, ax=1120, ax=1121, ax=1122, ax=1123, ax=1124

v0.5
  - Reimplement the tables so it is compatible with the video save pointer table
  - Implement the remaining functions (don't know if all are needed):
	- set border ah=0b bh=00, set cga palette ah=0b bh=01, 
	- display switch interface ah=12 bl=35
	- video refresh control ah=12 bl=36
        - save/restore state ah=1c

v0.6
  - Graphic modes
  - Implement the remaining functions :
	- read/write graphic pixel ah=0c, ah=0d, 
  
v1.0
  - Bugfixes


Long term :
-----------

v2.0
  - upload the fonts to the "card" memory 
  - display fonts from the "card" memory (plex86/bochs vga card needs update)

=================================================================================================
VBE:
----
Short term:
- bugfixes for bochs 1.4(+) support
- implement remaining functions that can be done with DISPI 0xb0c0 interface 
  (get functions for mode?, window)

Long term:
- extend DISPI interface (see also bochs bug [ 529554 ] unsupported VBE features DISPI update)
  . clear / preserve display memory upon set vbe
  . set/get logical scanline length (4f06)
  . set/get display start (4f07)
- have plex86 host side display interface
- support more modi (16bit/32bit modi support)
