Components won't help here as the compiler is too interconnected (though 
the CPU directories look rather nice ^^).

I've written a little tool some weeks ago which uses fcl-passrc to 
extract the unit dependencies and prints a dot file which can be 
processed by Graphviz. With this I wanted to check where we might have 
cycles and if we could fix their detection, but for now I've given up, 
because the graph is to messy. As a next step I planned to implement a 
Circos (see http://circos.ca/images/ ) backend for that tool...
