Fix 82875 PCI setup

The 82875 EDAC driver enables an otherwise-hidden PCI device, but doesn't
register it as a PCI device properly.  Therefore, the device list in
/proc/bus/pci/devices is different than the tree in /sys/bus/pci.  This
usually manifests as the X server failing to start, since it expects the
two lists to be consistent.
