With regard to the logout, I too had the problem of it hanging. I edited /usr/bin/icemaemo and take the backgrounding off of /usr/bin/icewm-session and put /usr/local/bin/startmaemo at the end of the file, so it looks like this :

export PATH="/usr/bin:/bin:/sbin:/usr/sbin"

/usr/bin/icewm-session

/usr/local/bin/startmaemo


I'm not 100% sure this is the proper solution, but it does fix the problem for me.
