I think that the Linux distributions are not going to build a special

Distros will generally turn on everything. You could have it on by default
if the kernel is built for CONFIG_X86_GENERICARCH which enables support for
other big numa configurations. I think distros generally build with that
enabled anyway.

config X86_GENERICARCH
bool "Generic architecture"
depends on X86_32

Ah, overlooked that.

OK, well, either way it still needs to be a separate config option.
