The old value 0x3400 gave the INTCA and INTCS interrupt conrollers separated spaces, but required ARM support for more than 512 NR_IRQS which is not in place at this point. The value 0x2200 will make some of the INTCA interrupts make use of empty INTCS areas. This is a bit more error prone but works fine as a workaround for G3, G3 and AP4.
