dell-smo8800.ko compiles and loads with trusty kernel. A '/dev/freefall' will be created if there's a SMO8800 or SMO8810 available. We'll need a userspace tool to work with it though.

Works if there's an SMO8800 or SMO8810 in /sys/bus/acpi/devices/. The dell-smo8800 is already merged in kernel 3.16, so you'll need an utopic kernel to use it at least for now.
