That's an even better idea than running x86-32 on x86-64 because it
better emulates a whole 32-bit environment.  I'll see if I can
set up such a beast on my box at home.  Unfortunately, KVM+Qemu has
been pretty flaky for me.

It's not hard.  Basically, you set up a buildbot and then contact Daniel to
exchange unique identifiers and passwords that he enters into the buildbot
server and you set up on the client.
