I have looked through the lx800 datasheet [1] and did not found any
hint about SMI triggering. If
that would be the case linux would need to do this too?!

But okay... as I need to get flat panel support working really soon, I
will go an other way
and will leave this and build wrapper functions like read_vp(..) -
similar to the linux ones.
In the end I would like to use most of the code from the linux fb driver.

On the other hand I will try to find someone how uses the vgabios on a
geode with a vga connector.

I know that geode vbios was created during gsoc and I am wondering if
there are any documentations
or anything else available?
