I'm blogging a Sartoris tutorial, it can be found at http://sartoris-microkernel.blogspot.com.
After a little bit of tinkering, Sartoris could boot the test image (Oblivion) all the way with paging enabled. I belive this is a huge milestone!
microkernel support for paging is almost done. all that is missing is to update inter-task communications.
see sartoris-0.6.0-pre9.tar.gz if you are interested.
the microkernel source code is now available at cvs.sartoris.sourceforge.net
