I think my laptop (x86-64) uses the same notion of suspend as Android.
I am confused now. Android 'suspend' is equivalent to
'echo "mem" > /sys/power/state'

Which distros call it "low-power mode with different wakeup rules"?
Gentoo doesnt. In KDE/Gnome it's also called suspend or suspend-to-ram
iirc.
