As far as I am aware, there is only 1 firmware version for the PIC used on the kipper rev 6 risers. You guys also have to remember that stock CD32 PSU can't drive every keyboard, since they tend to draw a lot of power. So it might be that the keyboard you have is perfectly fine but the PSU simply can't provide enough.

For example, look at the bottom of your keyboard how much power it draws. I've seen from 50 mA to 150 mA, nd none of them give me any trouble when powered through an AT 250W power supply, but they might if I had the stock CD32 PSU.
