I'd like to suggest adding dt2w and s2w support.
The relevant files for faux kernel are in /sys/android_touch:
doubletap2wake
doubletap2wake_version
s2w_s2sonly
sweep2wake
They are all toggles 0/1.
Alternatively I'd suggest adding a full /sys/ editor to let the user manage unsupported settings. Some tuners allow to add custom settings to the app by choosing the relevant sys file.
