If I am not mistaken you need to modify the driver to work in your case.
remember the mods that you did to the driver??

It doesn't matter for now because we are not doing byte or word swapping.


In the same routine there is this comment:

/* FIXME: why set colorbars for 1 instant ??? */
	bt848->color_ctl = BT848_COLOR_CTL_COLOR_BARS;
/* FIXME: undone 4 lines later, why bother ??? */
	bt848->color_ctl = BT848_COLOR_CTL_GAMMA;

Careful here because some of this stuff was written after I read 
Brooktree's DOS demo. Some of these chipsets are cranky and yes
we can experiment by taking the lines out.

I am going to go thru the driver and examine each FIXME comment.
