This looks good (and doesn't seem to introduce any 'make htmldocs'
build issues on my machine).

You could also mention that using --arch=x86_64 (or similar) instead
of the UML options is another, equally viable option for running the
tests. That'd make it more obvious how to run on different
architectures: UML, while a good default, is quite different to other
architectures in not having any PCI support out-of-the-box.

(Maybe we should make the --arch=um default config include these
options? Or have um-pci as another architecture. We did decide not to
bother with SMP and x86, though...)

Regardless, this is
