The question is what is the maximum frequency you can send messages with your keyboard?

Particularly interested in: the frequency with which it is possible to flash the LEDs (caps for example)?

The issue is not associated with the upgrade of iron — are only interested in the possibility of a software implementation.

The answer to the question is necessary for idiotic ideas "abnormal programming" to write the dimming of the diodes on the keyboard (something like a PWM).

The clock frequency of the PS/2 20-30kHz. Roughly speaking 30Кбит ideally, and need to send bytes and it takes time to switch. Very roughly estimated received no less than kHz "PWM".
I think you can try :)
