I think so. However, I built kernel with device iic, iicbus, iicbb, but 
nothing shows. As said, I am doing my 'homework' now - astudying sources, 
but, as usual, any help appreciated.

So it means we need either hack pci_isa pridge to recognise and work with 
geode's LPC bridge or build new PCI - LPC bridge. When I will have some LPC 
peripheral available, I will do some tests. Until then, i2c support has 
higher priority - can be tested just now and could bring something when 
working.
