The PCI device tree names under /proc/bus/pci have changed to the
format of:
/proc/bus/pci/$(PCI_DOMAIN_NUM):$(PCI_BUS_NUM)/
instead of the old:
/proc/bus/pci/$(PCI_BUS_NUM)/
X's device probe has never been fixed to handle this correctly.
It really needs this fix, as X is busted on multiple platforms
with 2.6.x kernels because of this.
