Whilst thinking on the autobuilders, I'd love to relax the constraint that this depends on the at91 subarch and at least allow build testing. Will greatly improve our test coverage. Maxime, I ran a quick test and it's fine on x86_64 anyway. Do you know of any reason we will get build problems on other platforms?
