Just installed new kernel 4.12-rc2.
ELAN touchpad is still completely dead on my ASUS G752VS, now it's not 
even present in my system settings.
Dmesg output and other details attached here (comment #66):

I read the whole threads. It's normal there's no interrupt observed if
using elan_i2c driver. It should use hid-multitouch.

I would like to know if there's any interrupts observed when it load
hid-multitouch driver instead of elan_i2c driver.

Something noted here, on my G752VSK the input device shows as ELAN1200
not ELAN1203. Although I think it should make no difference, just to
note that my machine maybe a little different from the bug reporter's.

Can you provide information Chris asked?
His G752 uses a slightly different touchpad so more information is 
needed.

Thanks!
