Hi all, i have a couple of questions.

I install the power kernel settings, reboot and open xterminal, type sudo gainroot, then type kernel-config show, and gives me this error: "this kernel version 2.6.20-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 an boot to active it"

How i boot and activate it?

I have rebooted my n900, then opened xterminal and follow the lines in the tutorial several times. I have reinstalled the power kernel settings and rebooted again, but xterminal is still showing the same error message every time.... i searched and didn't find a solution, so please help.

Many Thanks in advance!

EDIT:
P.D. i have installed multiboot and nitdroid, and the sock kernel
