This patch changes the order in which partition types are detected,
which matters when multiple partition types match (a GPT often/always
has a protective MBR too). Consequently, this breaks GPT support.

By hacking around this (turning off DOS partition support), and fixing
the PCIe issue I mentioned elsewhere, test/py seems to work for me with
this series applied.
