--Edited kernel config to have rotary_encoder built as a kernel module by running 'make xconfig' from ~/build/linux-omap-3.5 (dot in checkbox indicates build as module, vice check mark that indicates build into kernel), then compiled (all) kernel modules by running 'make ARCH=arm CROSS_COMPILE=<EMPTY QUOTES> modules' from same location. ** Module would not load via either modprobe or insmod--need to research error messages more--possibly compiled with wrong command or need Module.symvers somewhere while compiling.
