I'm not sure about that one. If we don't support reserved regions for
MSI, why should we return "true" here? My gut feeling is that it should
be false (because we lack the infrastructure to deal with it).
It is a bit of a moot point since the only calling site will *not* call
this in that case, but I believe that we should be consistent.
Eric, what do you think?
