1.3.8 lists use of RFC1918 address space as one of four possible
implementations, immediately after the phrase "may include, but are not
limited to".  I don't interpret that as "pretty much requires RFC1918".

Now, if you'd like to claim that 1.3.8 is completely useless, I won't argue
with you -- it's security-by-obscurity of the worst possible form.  But
don't blame PCI compliance for any inability to deploy IPv6, because it just
ain't true.
