Hmmm ... I haven't done alot with ACPI but I'll go take a look.

This seems to handle the drivers ... but the issue of the other
initcalls remains the same?  What do I do with layers above/below
the device calls (note, that some of the calls you list above are
NOT device_initcalls, but subsys_initcalls in order to get the
driver load order correct)?  What about non-device level
initcalls like sn_pci_init?

I suppose I could in that once instance use ia64_platform_is.
But then we're in the same boat we were in earlier ...
