It's the same. Some architecture have 36-bit addressing, but I don't 
know if the latest kernel has the support for this feature for powerpc.

I think recently there were some patches with 2.6.26-rcx to support
36-bit addressing and changed the addressing to phys_addr_t type from
unsigned long, and few other changed. I think this should be available
starting 2.6.26 version.
