XOR it with another free running oscillator of about the same frequency  
but with a bit of frequency modulation dither added.

It would be so much easier to do in a PIC or with a shift register.

Yes, but the essence of my original question is how to create "dither"  
or a degree of randomness at ELF.

Perhaps you could use a electronic tea light.  
If you prefer to build it using standard chips then consider using a noice generator
with a BJT.
