When you boot a kernel with MPVERBOSE or use boot -d and
"w mp_verbose 1", what does it give you as ISA overrides?
I have a report with issues for the very same chipset, where the ISA
overrides for IRQ 14 and 15 force edge interrupts. That's the note in
parenthesis from ISA interrupt override.

I would expect it to use either the LAPIC or IRQ 0 for that, which is
why I asked. We don't currently have a good mechanism to include
properties to tell the IOAPIC which interrupts to configure correctly,
that's why I am inclined to not want to revert this.
