I suppose it could be turned into a compile-time/runtime configurable
option when VT-d emulation arrives. Unless you mean having both IOMMUs
run at the same time, which is impossible unless some meaningful
topology is specified (presumably hardcoded as well).
Considering this is only a machine model I'm modifying, it's just like
other emulated pieces of PC hardware that are (at the moment) hardcoded.
