			== Upstream kernel with Maemo 5 ==

			1. Kernel patches from https://github.com/pali/linux-n900

			2. CSSU-Devel from http://talk.maemo.org/showthread.php?t=84292

			3. BME-Replacement from http://talk.maemo.org/showthread.php?t=93183

			4. Fixup for wifi firmware:

			ln -s ../wl1251-nvs.bin /lib/firmware/ti-connectivity/wl1251-nvs.bin

			5. Fixup for Dialer application (rtcom-call-ui):

			Create new file /etc/event.d/userspace-fixes with content:

			start on started hildon-desktop
			service
			console none
			script
			if ! hal-device /org/freedesktop/Hal/devices/platform_soc_audio_logicaldev_input 2> /dev/null; then
