Just FYI on the Geodes in case anyone missed them...
The AMD Geode dev site has a few handy utilities and tools for debugging BIOS and driver settings.
Cyreg - Cyreg is a menu driven utility that displays memory, I/O and PCI configuration space data. The menus are defined in a text file that allows the user to easily modify each menu.
Loadreg - Loadreg is a command line utility that allows the user to read or modify any I/O, memory, or PCI configuration space location. It is ideally suited to modifying system registers via a batch file.
MCVAL - Mcval tests the state of the memory controller against known values, as well as lists all supported processor speeds and their associated memory controller register values.
