[edit] 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: 

mkdir -p /lib/firmware/ti-connectivity
ln -s ../wl1251-fw.bin /lib/firmware/ti-connectivity/wl1251-fw.bin
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
