There are some problems with ppb msi interrupts. For instance, i386 in
some situations can run out of vectors. On amd64, there is at least one
machine that fails to resume. Yes, those problems need to be fixed. But
other problems should be found, too. If we leave ppb msi off, we won't
learn anything new. So use an #ifdef to enable ppb msi for non-i386,
temporarily.
Kind of discussed this with kettenis.
