Unless your hardware provides BIOS for driving it like a vga/svga you will
probably need to write (get some else to write) a display driver
specifically for it.

For the Psion stuff the screen is just memory mapped and I wrote a simple
driver to render text (all 8bit wide) directly onto it. This unfortunately
requires a font to be held somewhere in the memory (in the kernel code
segment for the psion though I'm thinking of moving this).

I was thinking that it would be better to abstract a little from this and
try and get a 'framebuffer' style interface going. This would help
development on various platforms that don't have a vga/svga plug in card.
Presumably all our frame buffer would need to do is simple text (console 8*8
??) and dots & lines (micro-windows).

Does any one else have any thoughts along these lines?
