Well, if the IIfx is anything like the IIsi in terms of Oscillator layout, I'd say
that oscillator is probably in charge of some subsystem on the motherboard. Perhaps
video, as sound does not require a 40mhz oscillator. It's obviously not for the
processor, though.

Does anyone know about the exact function of the 40MHz-clock-oscillator
on the motherboard of Mac IIfx?
I replaced both the CPU as well as the FPU by their 50 MHz-versions and
put in a 100MHz-oscillator instead of the original 80MHz-one. Now, I
wonder wether the 40MHz-one should also be replaced by one running at
50MHz.
Any advice will be most welcome. Steff
