DSL-N :: DSL-N and Xdmx

I recently installed DSL-N 01RC4 onto my hd and then installed the Xdmx package from sourceforge.
But i can't seem to get it working.

Does anyone have an idea how to setup Xdmx + Xinerama onto DSL-N keeping the number of megabytes down ?

Or point me in the right direction because i am kinda lost.

thx
