unsigned long? u64 differs for 32-bit and 64-bit.

Doh, if you would put the whole resource range there, you could use %pR ;-)

This is proper.  This is a 32-bit only platform (and the format is  
long long).

Sorry, I meant `unsigned long long'.

One day someone may copy-and-paste to a 64-bit platform...
