Fix XFree86 X server's PCI bus support code to be able to cope with both

+checking for the 2.4 style first.
-This patch by Daniel Seyffer and Ciaran McCreesh.
+This patch supersedes one by Daniel Seyffer and Ciaran McCreesh, which had
+problems on some systems. Quoting David Mosberger:
+ [That patch] is keeping X from working on my machine. That machine is a bit
+ unusual in the sense that it has no PCI bus numbered 0:
+
+ $ ls /proc/bus/pci/
+ 40/ 60/ 80/ 81/ devices
+
+ Due to this, the workaround for bug #225526 actually ends up breaking
+ X on my machine:
+[...]
+ So, on my machine (bus is < 256), the stat("/proc/bus/pci/00", &ignored)
+ call fails and then X attempts to use PCI-domain numbers,
+ which is wrong for my machine.
+
+ As far as I know, it is bogus to assume every machine has a PCI bus
+ numbered 0.

+This patch by David Mosberger.
