Subject: [PATCH] Disable debian pci-id-list autoconfig code on non-linux.

It contains static paths, fails to build on non-glibc, and apparently just
exists to support distributions managing binary drivers and open-source drivers
together.  Also restores previous code for fallback to vesa if nothing is
detected.
