Sorry, my fault. kernel/power/disk.c:power_down(): it calls
device_shutdown even in PM_DISK_PLATFORM case. I thought it would do
device_suspend() to enable drivers doing something more clever.
So only missing piece of puzzle seems to be making sure disks are
properly spinned down in device_shutdown... and even that seems to be
there, not sure why it was broken before.
