Currently relies on the native video mode being passed in from the BIOS.
No EDID, etc support, although most TFT's don't offer it

Finlay my i855 works. I still have a black board on top of the screen that
don't show up on a print screen.
nearly fixes (if the black thing in top can be removed it would fix my
problem)

after some more testing it looks like the black top board are getting
updates when I move windows around (it's more gray dotted now.. or bad EGA
resolution)
I have also found out that I can stretch a window the same length out of
screen in the bottom as the black thing at the top.. so perhaps the screen
need to move up 0.5 - 1 cm
Nice work..
