Yeah, IBM sold a couple of these "interesting" 32-bit NUMA machines:

I think those maxed out at 8 nodes, ever. But, no distro ever turned NUMA on for i386, so no one actually depends on it working. We do have a bunch of systems that we use for testing and so forth. It'd be a shame to make these suck *too* much. The NUMA-Q is probably also so intertwined with CONFIG_NUMA that we'd likely never get it running again.
I'd rather just bloat page->flags on these platforms or move the sparsemem/zone/node bits elsewhere than kill NUMA support.
