Confirmed this bug on Acer Aspire 4741G-434G50Mnkk. In response to Markhor's post (#11): I wonder whether the laptops in question really have dummy interfaces (thus needing to be added to the blacklist), or if the interfaces are valid and the method WMID_set_capabilities() is the source of the trouble.
I know that on my Aspire the multi-gesture trackpad (detected as an ALPS trackpad by Windows) is detected as a generic mouse by Ubuntu. I can't help but suspect the failure to complete the acer-wmi device detection at startup is responsible for this and am not sure that adding the laptop to the blacklist is the final solution. I'd like to get more functionality out of this trackpad, if the problems are related. Anyway I'm just thinking out loud here. I don't really have enough experience in Linux/kernel hacking/etc. (or time for that matter) to test this.
