Hi After installing Umay12 and start my phone and displayed multiboot, I noticed that the kernel of nitrdroid(2.6.28-07_rc3_armel.deb) has replaced kernel-power46 of maemo with old kernel 2.6.28-omap1.Do not know if anything else is this change but I have not installed before nitdroid and I think that only nitrodroid.Interested should know after installing nitdroid then install kernel-power46,and after installing kernel-power46 not again become an exchange with the kernels.I hope I've explained my problem properly
