WRT passing noloop that laptop has a weird i8042 implementation where the kernel does not detect the aux port at all unless noloop is passed, a patch to do this automatically is already upstream: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/drivers/input/serio/i8042-x86ia64io.h?id=9ff84a17302aeb8913ff244ecc0d8f9d219fecb5 WRT needing to pass psmouse.proto=bare, that should not be necessary with recent kernels, but the fix for this has only gone upstream very recently, so likely he is just using a somewhat older kernel.
