Can you use -2 instead? And define manifest constants for them? There exists DMA hardware that does not use DMA 0 internally, for which it would be an allowable address. Admittedly, this is mostly non-Intel hardware, but the design shouldn't be so restrictive as to not allow for non-Intel hardware.
