I just want to confirm that the 8086:1503 (Intel 82579V) is present on
my motherboard (ASUS P8Z68-V PRO GEN3 fw v3402) and these new patches to
blacklist interrupts didn't cause any damage/breakage. From what I can
tell I can't notice any slowdowns either (using a simple stopwatch
approach).

I would very much like to know what is missing for this thing you
suggest here to actually work. Because it does seem to be an even better
"default" chainloader than undionly.kpxe currently is, as it would
include fallback if native drivers aren't available.
