For better or worse, Linux often takes on the responsibility of
working around firmware bugs. This is a real issue that affects
multiple Asus laptops; you'll have no touchpad input upon reboot from
any OS that drives the touchpad in "generic hid" mode (e.g. older
version of Linux, some embedded OS, etc).

If the sleep is really that controversial, we could make it specific
to the ELAN1000 model that is the one in question here?
