Perhaps on a related issue, when I use the 'GetSystemInfo' command under
WindowsCE on my Philips Nino, it tells me that the processor is of R4000
type. That's a contradictino if you use the System Information dialog 
provided with the Nino. I would tend to backup up R4000 similarity as
well. However, maybe that's not good reasoning :). Just my 2 cents.
