I see.

Maybe we should pack that stuff in a subdirectory of those
platforms that need it. 

Dropping long long arithmetics is not an option as we need 64bit integer
variables in the OpenBIOS forth kernel to comply with IEEE 1275-1994.

Going to some non-native implementation would probably be doable but it
would also make the thing unneccesarily big and slow.

yes, the parent node needs a decode-unit and encode-unit method. See
drivers/pci.fs
