Particularly, on a laptop that has an integrated touch pad, I'd like to select the external mouse port. This document http://www.synaptics-uk.com/decaf/utilities/ps2-mux.PDF describes what appears to be a rather well thought method for multiple aux devices on a single KBC. Looking through the kernel sources, I see no handling for this. From a big picture perspective, how does Linux handle a system with an integrated mouse pad, and an external PS/2 mouse port? Is this whole Synaptics idea dead, or is support for this planned, or even considered? Does any one have any knowledge the number of KBCs with this muxing? Seeing some of the parties that partcipated in the standards, it would be a touch surprising if it just completely died. --jc
