OK, fair enough. But that's a quirk of the x86 architecture that you're pretty tied to -- you don't actually need MSI, you just need the interrupt numbering that is enabled on x86 with that config option.
Since Niagara boxes don't have HT anyway it's kind of a moot point. Although I wonder what you would have to do to make your device work with something like the MIPS SoCs that have HT...
