Yup, for sure.  It's also interesting how much code ppc64 removed when
they did this:

http://lists.ozlabs.org/pipermail/linuxppc64-dev/2005-November/006646.html

Please cc me on patches.  Or, if nobody else was planning on doing it, I
can take a stab at doing SPARSEMEM on one of the arches.  I won't be
able to _run_ it outside of qemu, but it might be quicker than someone
starting from scratch.

Was it really just m68k and parisc that need immediate attention?
