Thanks for your reply.
0. All test result is based on Ubuntu 14.04.3 with 4.3.0-040300rc5-generic #201510111530 SMP Sun Oct 11 19:31:35 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
1. The psmouse module is still there after resume
2. Nothing happens when I reload the psmouse module
3. Yes, I can apply the patch and build the kernel on my own
4. I wonder that there may be a bug on ASUS's BIOS, because there is a switch called "Internal Pointing Device" in the BIOS(UEFI) setup menu.
And there is a special touchpad driver called "ASUS Smart Gesture" for windows.
I had send a mail to the ASUS Support, but they refused to give any support for linux.
5. The full lsmod list is as below, maybe block some module will solve the problem.
