A major problem is that distros don't seem to be willing to push 64-bit
kernels for 32-bit distros. There are a number of good (and
not-so-good) reasons why users may want to run a 32-bit userspace, but
not running a 64-bit kernel on capable hardware is just problematic.

I work for Intel. I don't speak on their behalf.
