Yes I do have CPU_GEODE in my kernel and I see the geode MFGPT probed in 
the verbose dmesg output. I'm not sure how I can tell what piece of 
hardware /dev/fido is linked to but I think you're correct and I'm using 
the geode watchdog and not the winbond chip. Maybe this has something do 
with me not having 'device eisa' in my kernel config!

I'm going to start compiling a new nanobsd image right now with eisa and 
the newer wbwd.c driver and see how it goes.... Thanks
