Looking at /sys/modules/acer_wmi/parameters/ec_raw_mode=20 contains a Y. The mousepad remains unresponsive on boot prior to a=20 =46n+F7. I've added options acer_wmi ec_raw_mode=3D1 (note the acer_wmi= vs=20 acer-wmi) simply because the sysmodule was also underscore. There is no= =20 difference, the module parameter is recorded as Y and the mousepad stil= l=20 does not work on boot. I will provide the other requested information soon.
