You need something like this.

My case is just the opposite of yours. I still depend on KDE3. KDE4 is still
in the test phase for me.
Here's what the session file looks like.
[EMAIL PROTECTED]:~$ cat /usr/share/xsessions/kde4-svn.desktop
[Desktop Entry]
Encoding=UTF-8
Type=XSession

One thing to notice is this:
export KDEHOME=$HOME/.kde4-devel
I can't risk my .kde/ folder. So for now, everything KDE4, should go
into .kde4-devel
There's one problem still. Some of the KDE4 applications fail. I think the
following variable is not the only thing that suffices the requirement.
export LD_LIBRARY_PATH=$KDEDIR/lib:$QTDIR/lib:$LD_LIBRARY_PATH
Even though this is set, I still need an ldconfig done to get all KDE4 apps
to work properly. So when switching back to kde3, I again need to run
ldconfig to disable the kde4 libraries. I'm not sure if there is any
simpler way to fix this.
Basically, when the session begins, DESKTOP_SESSION variable gets kde4-svn.
And that is what I base all my assumptions on.
HTH,
Ritesh
