After reflash on a clean system 21.2011.38-1 and installed cssu-thumb, what packages from kernel to install? Linux kernel for power user (settings and overlclock) and Linux kernel for Community SSU (boot image for u-boot and multiboot)? I just installed automatically the package Linux kernel for Community SSU 2.6.28-10cssu3. Linux kernel for Community SSU (boot image for u-boot and multiboot) will not install in application manager. Installing Battery Patch and Speedpatch is still useful? Battery Patch wants to install a dependent package Linux kernel for power user.
