What I read in case the touchpad is not working is that no one is trying to read from it. The irq might not be even requested, so no one can get events from it. It might be a command missing, but to me the problem lies after the i8042 controller has been initilized.
BTW your analysis is correct (minus the translations that I could not check), so the problem comes later when the psmouse driver tries to probe the touchpad.
