1st: Download and install all packages from here

Code:

dpkg -i kernel-power_1:2.6.28-10power48_armel.deb
dpkg -i kernel-power-modules_1:2.6.28-10power48_armel.deb
dpkg -i kernel-power-flasher_1:2.6.28-10power48_armel.deb
dpkg -i kernel-power-settings_0.12_armel.deb
dpkg -i kernel-power-bootimg_1:2.6.28-10power48_armel.deb

check if it's installed properly with

Code:

uname -r

is should say 2.6.28.10-power48

then follow up this little guide (thx to [darkgunman] and fabry's guide of patching power-kernel with u-boot)

open terminal:

Code:

sudo gainroot
cd /home/user

# prerequisites

Code:

apt-get install -y wget flasher mkimage

#1. Download power kernel deb file from repository and extract fiasco image from it

Code:

wget http://bigbob.fun.free.fr/maemo-kernel-power/kernel-power_2.6.28-10power48_armel.deb -o kernel-power_2.6.28-10power48_armel.deb
dpkg --fsys-tarfile kernel-power_2.6.28-10power48_armel.deb | tar -xf - boot/zimage-2.6.28.10-power48.fiasco
mv boot/zimage-2.6.28.10-power48.fiasco /home/user/
rm -r boot
rm kernel-power_1:2.6.28-10power48_armel.deb

#2. Download matan's u-boot from repository (it is named u-boot-for-power-kernel) and extract file image from it

Code:

wget http://repository.maemo.org/extras-devel/pool/fremantle/free/u/u-boot-for-power-kernel/u-boot-for-power-kernel_1.0_all.deb -o u-boot-for-power-kernel_1.0_all.deb
dpkg --fsys-tarfile u-boot-for-power-kernel_1.0_all.deb | tar -xf - ./usr/lib/u-boot/u-boot.bin.0x38000/u-boot.bin.0x38000
mv ./usr/lib/u-boot/u-boot.bin.0x38000/u-boot.bin.0x38000 /home/user/vmlinuz-2.6.28.10-power48
rm -r usr
rm u-boot-for-power-kernel_1.0_all.deb

#3. Unpack fiasco image

Code:

flasher -u -f zimage-2.6.28.10-power48.fiasco
rm zimage-2.6.28.10-power48.fiasco

#4. Transform zimage in uimage (necessary because u-boot boots kernel only in uimage file format)

Code:

mkimage -a arm -o linux -t kernel -c none -a 80008000 -e 80008000 -n "power kernel v48" -d zimage uimage

#5. Add power kernel uimage at end of previous file (starting write at offset 0x38000 aka 448 blocks)

Code:

dd if=uimage of=vmlinuz-2.6.28.10-power48 seek=448

#6. Remove zimage & uimage

Code:

rm zimage
rm uimage

#7.1 flash the kernel

Code:

softupd -vv -s --local

#7.2 open a new terminal (shift+ctrl+x) leave other xterm open!!!

Code:

flasher --local -f -k /home/user/vmlinuz-2.6.28.10-power48

#8. Optional - multiboot - backup and replace power48

Code:

mv /boot/zimage-2.6.28.10-power48 /boot/multiboot/vmlinuz-2.6.28.10-power48-bak
mv /boot/multiboot/vmlinuz-2.6.28.10-power* /boot/multiboot/vmlinuz-2.6.28.10-power48-bak
mv /home/user/vmlinuz-2.6.28.10-power48 /boot/multiboot/vmlinuz-2.6.28.10-power48

#9. Optional - clean multiboot entries
if you have old power47 or double power48 entries
open filebox and navigate to /etc/multiboot.d to delete the respecting *.item files.

#10. reboot and watch the !!! :d

edit: I coloured the code for whose who don't know what goes together and what not. So, each colored lines are a complete string where to hit 'enter' after. I left the obvious ones untouched

greetz,
