The touchpad on Acer Aspire 5720, 5520 and some other Aspire models (signature 0x73, 0x02, 0x50) has a button that can be rocked in 4 different directions. Make the driver to generate BTN_0..BTN_3 events in response. The Synaptics driver by default maps BTN_0 and BTN_1 to up and down, so there should be no visible changes with the old setup that generated BTN_FORWARD and BTN_BACK (also mapped to up and down).
