misiak, I was trying the same method earlier, the same way u mentioned in the noob guide but to no avail. I cannot get 2.6.68.10pali1 to boot. I can boot only to Maemo PR1.3 and NIITDroid Vostok.

When selecting option to power kernel, the N900 does not seems to flash the kernel area with the power kernel and it just gets stuck in a black blank screen..
I really needs power kernel for hostmode and many other features..
The /lib/modules, /boot/multiboot and /etc/multiboot.d seems fine with same reference to kernel.

I do not know where i am doing wrong :-(
