If you end up having to write two whole drivers that sounds enormously
depressing especially for those of us working on devices that aren't
architecture specific.  We've managed to avoid that thus far with device
tree and platform data, would it not be possible to mandate that people
use ACPI in a vaugley sane way which can support this too?
