Comment 18 for bug 1234743

i cut that down to http://paste.ubuntu.com/6217518/, applied it and built a kernel ... sadly now Mir does not start at all, SurfaceFlinger does, but is very slow and complains:

W/SurfaceFlinger( 659): Timed out waiting for hw vsync; faking it

so i guess for using this patch some changes on the userspace side to actually use sysfs instead of uevents is required
