Hi! Starting Maemo with mainline kernel is not possible. But you can
patch Maemo (userspace) and apply some kernel patches and you could boo=
t
Maemo system with Hildon UI.

You need:

Patched kernel:
https://github.com/pali/linux-n900

CSSU-devel:
https://wiki.maemo.org/CSSU
http://talk.maemo.org/showthread.php?t=3D84292

Open source battery management:
http://talk.maemo.org/showthread.php?t=3D93183

=46ixup for Dialer application (rtcom-call-ui):
=46ixing HAL path /org/freedesktop/Hal/devices/platform_soc_audio_logic=
aldev_input

=46ixup for SGX video driver:
=46ixing script /etc/event.d/sgx

If you do not know how to fix HAL & SGX script I can send you later
needed information. But I do not know them right now.
