No, right now we more or less create a fake I/O APIC.  We don't have to deal 
with masking in the local APIC, boot strapping, or anything like that.

It makes writing tests easier but I think it makes supporting MSI a bit more 
challenging.  I'm not sure how well it will generalize to other platforms either.

That's one of the reasons I wanted to get an early version out to get some 
feedback on this.
