You seem to be recommending precedence for OF.  It should be
consistent across all drivers/sub-systems, so do you really think
that OF before ACPI is the way to go?

I just think it's more hackish to test acpi_disabled than to
simply see if the matching OF node even exists.

If ACPI is enabled, no OF node will be found.

It could just be my preference for such things.

I really wish it just fell out from the probing method, but
we're using PCI for that.
