Comment (by tqh):

 Perhaps a patch with just _PIC = 1 before installing the int handlers
 works just as well.

 I think the issue here is that _PIC = 0 and _PIC = 1 can be completly
 different configurations in the vendors ACPI impl, so migrating the
 interrupt handlers over isn't enough, you probably need to reinit the
 handlers or modify how ACPI and embedded controller init or install their
 handlers so that they do that with _PIC set correctly.
