So after I tried Spessotto's suggestion, I left it, then tried
blacklisting btusb (/etc/modprobe.d/blacklist), rebooted, removed btusb
from blacklist, removed asus.conf, rebooted, once again entered the
command

# echo "options asus_nb_wmi wapf=4" > /etc/modprobe.d/asus.conf

Rebooted... and, suddenly,

# hciconfig -a
hci0:	Type: BR/EDR  Bus: USB

# hciconfig hci0 up

This brought bluetooth up... But gnome-bluetooth was not recognizing it.
It turned out that I needed to roll back bluez5 to bluez4. I did so and
now it's working. So that leaves only the high cpu load.
