Quote from the linked page: "You’ll need a kernel with the Android patches (binder, ashmem, logger etc.)" [...] Neither Fremantle will run on Android kernel nor Android will run on Fremantle kernel. I think that sorta sums it up good enough.
Supposed there is static pm missing, what would happen while trying to run an Android app? //edit: Can't our Linux kernel take care of whole power management and our Dalvik app just let be controlled?
