Yep, that's certainly true! However, I have to admit that I'm
intentionally regularly testing all kinds of stuff on pure 32 bit,
because I think that most of the other "first like of testing", i.e.
the developers themselves, are primarily working with 64 bit these
days. So I thought it might make sense if someone keeps a little of an
eye on 32 bit - after all, in general and if there are no technical
reasons that speak agsinst it, things should work there, too. And
indeed, during the past year I've spotted a few little things that
were only causing problems on 32 bit - both in the kernel and other
components like systemd - and which could subsequently be fixed in a
relatively easy manner.

Right, I'll see what I can do over the weekend. So stay tuned for my
first ever proper (at least as far as the guidelines for submitting
patches are concerned) patch and expect the worst. ;-)
