sb/via/k8t890: add vga textmode code for k8m890 chrome igp.

Browse Source 
Add initialisation for the VIA Chrome 9 IGP on the k8m890 through native code
and through the general vga infrastructure i committed a month or two ago.
Add videoram_size option for k8m890 and the Asus M2V-MX SE.

Now the Asus M2V-MX SE will magically come up with a working standard VGA
80x25 textmode.

Many thanks to the people who worked hard on the Asus M2V-MX SE, and all
of its components; this vga bringup was a breeze thanks to your hard work
for this excellently supported board. And separate thanks to Rudolf Marek
for spurring me on and for providing a register dump.
