In this scheme, 'kernel drivers' doesn't just refer to the drivers for
hardware. It refers to anything remotely power management related,

Or even "cpu idle". Entering power saving modes shouldn't be such
a Big Deal. Some of the variable scheduling timeout work has been

haven't noticed a platform with more than 3 low-power modes so far,

An example of custom power states for the TI OMAP family.
/sys/power/states supports a state named "deepsleep", which corresponds
to the platform state actually entered by the present-day system suspend
handler. It no longer offers the option of "disk" suspend which would
not normally be available
