Yes, I am almost 100% sure that this affects suspend/resume. Prior to
the _REV hack, my laptop *never* suspended correctly. Now it
regularly suspends just fine. I also double-checked that rebasing on
Linus' master didn't affect it. With the _REV hack it doesn't
suspend. Without it, it's just fine.
I don't know much about suspend/resume but is it possible that the
problem is the kernel not being able to properly shut down the sound
card?
Thanks for that confirmation. That does sound like a very likely candidate that it was because the audio device was in the wrong state.
That matches what I've seen. With the _REV hack, I see nothing about
HDA in dmesg and I get different audio messages than with an _OSI of
Windows 2009.
I look forward to seeing the update. Thanks for working on this!

Sure. In in the interim, here is the patch you can apply to your local DSDT and put in the initramfs to see what it will look like w/ A02. This will leave the touchpad in I2C and audio in HDA.
