I have the same problem, but I don't have installed that you call fam, and I don't have NFS. In my computer: 1) When splash screen says "Initializating services..." it takes a lot of time in that position and after that the splash screen dissapear and only the mouse pointer is seen. 2) After a lot of time KDE starts and works well.
PD: I'd tried running fc-cache (and forcing) yet. Bye.
