I won't start with ModemManager, NetworkManager, or the driver.

I will start with ACPI code and trace from there.

ACPI does Power Management and 
implements the policy of sleeping states.

Not sure if the policy is extended up to ModemManager.

I don't know any more than this (without "doing the work",)
so just take this as one other suggestion that you can look into.
