In fact, you don't need that, CONFIG_NUMA is enough ... provided that it
builds at all, which needs CONFIG_SPARSEMEM (my previous test didn't
show the bug because the kernel build acutally failed due to the lack of
CONFIG_SPARSEMEM and I didn't notice).

I suppose we shoud fix Kconfig there ...In fact, sparsemem makes sense
to use on a G5 even without CONFIG_NUMA, provided that I add proper
support, so that the IO hole doesn't get struct page created ... 

I'll try to come up with a fix tomorrow, in the meantime, disable
CONFIG_NUMA.
