Patch by Mike A. Harris <mharris@redhat.com> to increase the X server's
maximum number of PCI devices from the arbitrary default of 128, up to the
PCI spec maximum of 256.  This is required on various different hardware
that exists nowadays on the x86, AMD64, ppc, ppc64 architectures, and
possibly other architectures.  In X.Org X11 6.7.0, this defaulted to 64,
while the current CVS head destined to become 6.8.0 defaults to 128.  We
just set it to the max to not have to deal with this again in the future.
