As I understand, Linux uses "ranges", although it's hard to be sure.
There are many references to "ranges" in Linux sources under
arch/powerpc, although many of them are pertinent to buses rather than
to the system memory.  Open Hack'Ware provides "ranges" for the memory.

As for yaboot, it uses "claim" both for its needs and for loading the
kernel.  And that's probably what GRUB could do.
