Not related.

Haven't applied a few driver patches yet because I have been working on 
the upper layer stuff.

Which brings up the point. The driver specific code for handing the 
flashing (acorn, atarti, and mac generic) driver shoudl move that code to 
there respected driver.

Cleaned up.

That is strange. I think it might have to do with the font height issue 
someone reported just recently. Before thee was a global variable 
video_font_height. This caused issues with framebuffer consoles since 
different VCs can have different font heights. Now it is private to each 
driver. This is probable related. I will test. I have a few more updates 
to vgacon coming later one.

The patch applied is the latest work from Monta Vista to get that chipset 
working on non ix86 platforms. As usual any changes to the Mach 64 driver 
affects a bunch of other machines.

Well you are using bleeding edge code here.

Haven't ported it over to the new api yet. I have been fixing the upper 
layer lately. As soon as I'm done I plan to do extensive house cleaning. 
Alot of the drivers where ported over as fast as possible and as such 
suffered.

That is the stable code. As for the white background that is strange.

Great. I don't think the driver supports dual head mode yet.
