Hi JM,

It has been some time since anyone has worked on Geode. You may have
to try it to find out. Before you do, make sure you have a way to
recover the BIOS image.

It is dated and the build process has changed, but you should read the
geode porting page. It talks about VSA and graphics and stuff. The VSA
was openned and used on the OLPC project. It requires the Microsoft
tools to build and no one has ported it to gcc yet. There is a link to
the binary on the geode page. You should stop by the IRC #coreboot if
you need a hand building coreboot.
