For me, they seem to be fixed for onboard devices, but not for devices plugged
into PCI slots.

I can detect when _SRS fails easily enough as you can do doubt see. What I
need is a way of reliably dropping back to a different configuration method
if _SRS fails. On my board, when I hack it to pretend theres been a failure,
I can't yet get the drop-backed-to mechanism to reconfigure any IRQs which
were configured with _SRS (even if it fails) properly.
