I solved my problem... I think. http://maemogeek.blogspot.com/2007/1...nto-nokia.html

I unpacked the FIASCO image and only flashed the rootfs, since I only had a software issue. And it works now! Just to test the WiMax. And I'm a bit concerned that the "About Product" says:
"Nokia N810 Internet Tablet WiMAX Edition <unknown>
Version: <unknown>"

There seems to have been in issue such that my hardware version is 1007 while the released image is for 1001. However, the About Product still sees the WiMAX MAC Address, so thats good.
