I wonder if the patch actually helps here now because the reason we want
to add it back is that it allows the CPU to enter lower power states and

when you have the patch applied?

No joy. I did not check what its actually doing, but the computer takes about 150mA over the charger at idle with screen off and 140mA in suspend. With mem_sleep set to "deep", it takes about 20mA in suspend. All with the battery at 100%, at 19.7V.

So I guess I want to keep the "deep" setting in my cmdline.
