VMX definitely does not (IIUC). I don't know enough about SVN to say for sure,
but my gut tells me that its not

The current code is geared towards using a user-mode (A)PIC. This patch adds
an "irqdevice" abstraction, and implements a "userint" model to handle the
duties of the original code. Later, we can develop other irqdevice models
to handle objects like LAPIC, IOAPIC, i8259, etc, as appropriate
