[Exim] 4.30-6.amwoody.1 + spamassassin problem

I did the upgrade to Exim4 finally on one of my Debian stable
boxes using ametzler's backports. (thanks!)
I can't get spamassassin working and I am using this guide:
http://www.win.tue.nl/~martijna/Debianstuff/

Below I have pasted my router and transport, the packages
installed, the order of my routers, spamassassin defaults,
and I use dc_use_split_config='true'.

Since I think everything is setup right, the only thing I am
unsure about is the order of the routers.
In the /etc/exim4/conf.d/router directory, do I need to make
a change in the spamcheck_router filename?
