Hello coreboot

     These initial patches enable booting with the SeaBIOS VGA BIOS on
Geode LX hardware.

     corebootv3-vga-msr.patch
         adds 3 vga legacy io routing msrs

     seabios-vgarom-geodelx.patch
         adds geodelx specific functions to the vgabios


     The rom will run from either coreboot/vm86 or SeaBIOS. When finished
"GeodeLX GPL VGA BIOS" should be displayed on the screen.

     My test hardware is an Artec Group DBE-61.  I have successfully
built and used the rom with gcc-4.1.2/binutils-2.17 and
gcc-4.3.3/binutils-2.18.  VGA functionality has been tested with the
linux vga console, svgalib utils, libpayload vga driver and SeaBIOS.  I 
have also confirmed that linux lxfb and Xorg function correctly after
the rom is loaded.
