I think our board is the thinclient RDK with the winbond superio duaght
board. Did you get the lastest code? Does it compile?

I haven't got that far yet. Probably somethin very similar to how we deal
VGA bios on Via.

My first impression is it can be done but the more I know about Geode and
VSA, the more I doubt it. One serious problem is there is basically no PCI
system in the Geode GX. All PCI configuration space registers are emulated
by VSA. It is possible to have a heavily modified driver to access the MSR
register space than the emulated PCI space but it requires a lot of work.

BTW, VSA is supposed to do some other magic device init too.
