--- Comment #15 from John Baldwin <jhb at FreeBSD.org> ---
I understand the cost of carrying diffs, but I've also been thinking about
power management of devices in FreeBSD and how it should work for native
drivers not just in suspend and resume for a long time, so I don't want to
promote hacks vs moving towards real solutions.

Can you give more details on how exactly the graphics devices uses the target
sleep state?  That is, is it using it to determine a Dx state to enter?  If so,
then providing the Dx state directly is probably more useful.  In particular,
for cases when we aren't doing a system-wide sleep (like 'devctl suspend foo0'
which you ignored), there isn't a system-wide sleep state to consider, only a
device state.
