Erm.. allow me, you folks ARE aware of the fact that vga16fb pokes around in the
standard VGA registers which not necessarily do the right thing for, say, LCD
panels...? This is no issue of a "broken BIOS" or the like. Many graphics
systems, especially those in laptops, use TMDS/LVDS or what-not controllers
which require specific setup, and are not bound to the VGA registers. vga16fb
has, naturally I might add, no knowledge whatsoever about such controllers.

Why do you think the X drivers have in many cases 100k of code only for display
mode switching...? :)
