The differences in the alpha platforms are mainly variations on how
the PCI bus is accessed and are more akin to the differences on the
x86 between using ACPI and pcibios to access the pci bus.  The low
level code such as what NetBSD would put in machdep.c and locore.s is
the same across all alphas.
