The memory base address you get from the registry is a phyisical address:
you have to use TransBusAddrToStatic to have it statically mapped
to a vitual address your driver can manage. Once you get this pointer
you can use WRITE_REGISTER_XXX functions
to access to your device registries.

You say that you insert the PCI device in a PCI slot and CE PCI
enumerator does not detect it?
Have you inserted the registry entries
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\PCI\Template\...]
for your device?
