I downloaded both the CentOS and puias
kernel-3.10.0-229.7.2.el7.i686.rpm packages, unpacked them and diffed
the config-3.10.0-229.7.2.el7.i686 included in each, they are identical
so it appears that puias has done *exactly* the same thing as CentOS to
get the latest kernel to work.

It might, but consider that if you're disabling a feature that is simply
not supported on 32 bit CPUs then someone using the 32 bit build can't
exactly complain if the kernel doesn't support it.  If it is available,
though, and just needs a bit of tweaking to get it to build for i386
then I would support keeping the feature and getting it to work so that
the i386 kernel is as feature-compatible with the x86_64 as is
reasonably possible.

I'd rather have a kernel and build that works, but is missing a feature
than nothing at all.
