At least as it is used right now, the ioport and iomem resources might as well be considered to be a "CPU bus", in the sense that they are organized around how a ia32 CPU sees the bus.
So in that sense it certainly would apply to MCA too.
However, this is something that might change later. IF we decide that we really want to make the resources be more oriented towards the bus addressing (which implies that we'd change "inb/outb/readb/writeb" too: this is a MAJOR change, and not likely to happen in the next few years), at that point MCA might either not be an issue any more or we'd give it a resource of its own..
So the answer is "at least for now, possibly forever".
