I managed to removed Nitdroid and then installed the kernel. When i try to run the command kernel-config load ideal , i get the same msg : "This kernel version 2.6.28-omap1 is not supported. Please make sure that kernel-power is installed and running. If you have just installed the kernel, you need to shutdown and boot to activate it.
To reinstall the power user kernel run : 'apt-get install --reinstall kernel-power kernel-power-flasher' ".

I ran the reinstall command, rebooted and tried again, still i get the same message.

Any other way to fix this?
