The patches to support it (still) haven't been merged.

Yeah; under ACPI, PCI does not act like it does everywhere else.
Nor does wakeup in general.

After sending patches to fix that for a couple years now, I'm
well past being tired of doing that.  I suggest it's overdue for
the ACPI team to get this part of their act together.

That is:  either start merging those patches, possibly with updates
to handle broken hardware better; or rewrite them; ... or just say
explicitly the message I've been receiving:  "Linux ACPI will never
support wakeup the way the rest of Linux can and does".  (And the
"why" should be something reasonable.)
