Choosing a random one sounds like a very bad idea, as there's no
guarantee that the driver X will choose factually supports the
hardware for which a PCI ID match was found.
Anyhow, the real issue is that generating random lists of "supported"
hardware, by matching every manufacturer and device ID found in the
source code, produces false positives, which is not desirable. In the
Geode's case, it results in entirely the wrong driver attempting to
claim hardware it doesn't support, which is what makes X fail.
