What leads you to suspect that the CPU I/O noise is random? The noise
generated by such comes from a chipset that operates at a given
frequency, which is powered by an AC source running at another
frequency, filtered through a power supply with capacitors, resistors,
etc. with their own set of time constant responses..
Otherwise the effort is to reduce all noise, so presumably it is less
difficult to let a certain of class of noise in. I believe what the
PCMOS folks are going for are voltage variations on (fixed resistance)
wires due to Brownian motion of electrons due to heat-- white noise.
There's always plenty of heat.
