Fix two of the extended memory hacks. The copy pages
routine in one place was setting the valid2 bit to
2 not 1. This meant the PTE was NOT valid and so
you would crash.
In Zero Page there was a incorrect setting of
the valid bit AFTER the actual zero (opps)..
Hopefully this will fix the 0xc0000000 crashes
that I have been seeing (unless of course there are
other problems with these old hacks of mine to get
to memory above 512Meg)
