You have to decide what you want: memory disk root or CF root. If you
want your root to be on a CF (wd0), then why do yo think you need the
memory disk? Just throw your kernel and all your binaries onto the CF,
make it bootable and everything should work (that's how I did it).
You could even leave the CF r/w, if you don't have too many write
operations to /tmp and/or /var/tmp
