I just installed the mer bootscreen and all I can say is...Woah! Hats off to whoever made it. It is nice.

I also have a few more additions. I was originally having trouble with getting the apt-get commands to install from the right repositories. I found out, I had to install them individually or I would always end up with jaunty packages instead of the preferred mer ones. Not really sure what is causing this other than I noticed some of the packages are only available in jaunty and this could be messing it up...but, for me, I could only get the apt-get -t command to work properly by installing packages individually. I had to actually type in the package version in order to get it to install the mer version of xserver-xorg-input-tslib.(Edit: you seem to have already noticed this and fixed it)

I could only get the hardware clock to set correctly by placing the same line that you added to hwclock.sh to /etc/default/rcS which should be fine since we're already adding the CONCURRENCY line to it too.

Also, mer-rescue-menu depends mer-omap-fb-splash which has a conflicting file with usplash which is depended by ubuntu-desktop. So, to install ubuntu-desktop mer-rescue-menu and mer-omap-fb-splash must be removed.
