This is all very interesting but what about power consumption and heat ?
Don't these things require serious thermal design to make them work inside
a closed box (especially the Geode) ? Last time I checked a chip running
at 300MHz requires serious cooling arrangements to keep it under 70C at
all times. Do they use a very low core voltage internally to avoid
producting heat ?

The application is battery powered, so I only have the MachZ running at
33MHz, and running some DOS applications. As far as support circuitry,
there really isn't that much!  The great thing about the part is the fact
that everything is integrated.  VGA is literally pins out of the part.
Same with PCI, ISA, IDE, RAM, USB, serial/parallel.  Pretty much only
passive components needed. Since then, I did another design with another
SOC, National Semiconductor's Geode processor, which is also a fully
integrated part, except it's a pentium core, and runs up to 300MHz!
