Hi - having troubles installing kernel power.

Transferred an old backup to a 'new' N900 with backup menu. That has stock kernel, so used HAM to install the kernel-power-flasher. Seemed to work fine, but after restarting the old kernel is still active (uname -a -> 2.6.28-omap1 #PREEMPT )

Also tried to uninstall and install a few times https://wiki.maemo.org/Kernel_Power#...g_kernel-power
Every time the same result. Any suggestions?
