The patch is unnecessary if the payload is SeaBIOS, which is the payload
you want to use to boot NetBSD anyway.  I barely remember the details of
the patch at this point, and I have no idea if I still have it laying
around.

Anyway, you almost certainly don't want to be relying on anything other
than the DSDT for interrupt routing on a modern machine with a modern OS.
