That would require statically generating some 961 Notify operations.
That seems a waste.
Similar to your v2 patch, it should be possible to dynamically
generate a second-level notify that does the equivalent of:
Method(PCN2, 2) {
If (LEqual(Arg0, 0x0101)) { Notify(S01_.S01_, Arg1) }
If (LEqual(Arg0, 0x0102)) { Notify(S01_.S02_, Arg1) }
If (LEqual(Arg0, 0x0103)) { Notify(S01_.S03_, Arg1) }
...
If (LEqual(Arg0, 0x011F)) { Notify(S01_.S1F_, Arg1) }
If (LEqual(Arg0, 0x0201)) { Notify(S02_.S01_, Arg1) }
...
}
Then the DSDT's PCNF method can have the intelligence to call both
PCNT() on the main slot and PCN2() in a loop for all the children of
that slot.
