@kaihengfeng: Patch applied on v4.11.9, booted from cold start (which has always shown the bug) without i8042 parameters, and my trackpad is working great! I'm happy to say this fixes my problem, will happily testify to upstream that it's a good patch, and would be delighted for us to mark this bug as closed. Thank you *so* much!
