Here's an argument for you: please save the environment by using only
64-bit hw. :-P

That's good.

What you could also do is build random configs on linux-next - "make
randconfig" - and see if you catch something weird there. And maybe then
try to boot them in a VM and see what explodes.

In general, testing linux-next is a very good idea because it helps us
catch crap early and fix it before it hits the official releases.

Thx.
