flameeyes, one of the gentoo council devs has posted a dirty hack on his
blog to have kde4 apps running on kde 3.5.


the problem is that this applies to gentoo so you have to adapt it to your
personal distro. the main points are the env vars, and the symbolic linking.
just be sure to make a copy of the old env vars and of the .kde dirs so that
you won't loose settings.
this hack will make a good deal of kde4 apps to start or autostart directly
on 3.5 instead of the default 3.5 ones.
