The reset button on PowerBooks essentially IS a CUDA switch - actuating the reset button on a portable Mac has the same effect as depressing the CUDA reset on a desktop; its effects are readily documented on this Apple support page.
In short, it forces the power manager to clear ALL of its settings, including date/time, and reload default values from ROM/the OS - pretty much the same thing that a CUDA reset does on a desktop.
