Nah, forget this one, we'll be remoing the whole io mask thing. It
doesn't work properly and has "issues" (we have case where valid PCI
devices have been allocated IOs in the first page and this IO mask is
not letting us access them for example).

The proper solution is to have drivers not try to tap hardware they
aren't supposed to. Mikey has a couple of fixes for parport and pc
speaker, other legacy stuff should already be pretty much fixed except
maybe legacy VGA which I still need to look at, but it makes little
sense to enable it for us anyway.

Ben.
