Well, 4.x does mask level-triggered APIC interrupts, but I'm not sure the boot 
interrupt is the issue as people have tried to turn the boot interrupt off 
and that didn't help. :(  I'm not sure why the interrupt aliasing is 
occurring.  I do wonder if it happens on Windows or other OS's and nobody 
notices.
