Just an untested idea:
If you have a spare output pin and a spare input pin, you could connect them with RC (resistor + capacitor) circuit. When the output pin goes to 1, the voltage on the input should rise according to V * (1 - e-t/(R*C)). Check for when the input value changes. The number of cycles, R, C, and V should give you the answer.

If you want a real McGyver solution:
Take a piece of radioactive material with short half-life, place it on top of the memory, and use the processor to count the number of random bit flips induced per period of time. Knowing the half life, the rate of change in the number of bit flips will give you the length of the period of time, which (with the known number of cycles taken by the code) will give you the frequency.

Freedom is the freedom to say that two plus two make four. If that is granted, all else follows.
