If I turn up debugging, when I `cat /sys/bus/iio/devices/device*/*raw*`, I see "iio iio:device3: accel_3d_proc_event" and I think that means that hid_sensor_push_data() is getting called.

You are saying there is some regression. This used to work and now it doesn't work. Is raw values are displayed correctly, when you do "cat"? If cat of raw values is working then power on of sensors is working. Turn on HID debug prints. If it is regression we can do git bisect. Any ACPI or PM changes can break this. Usually there will be GPIOs which will be involved in power on, where ACPI comes into play. This will be done by i2c-hid. There are some prints in i2c-hid which can be enabled also.

I don't know if this is a regression. I can try going back to an older kernel to see if the /dev/iio:device* files produced any output. Yes, the *raw* files in sysfs are producing output, that is changing as I move the laptop around.
