We have no reason to suspect that Apple's system controller is capable of handling a different FSB speed than RAM base clock (133mhz FSB => DDR-266, 166mhz FSB => DDR-333, etc), and I know that there is certainly no "PC166" RAM, so there is no known way for a PBook to run with a 166mhz FSB. Sure, in the future I suspect they will, but I do not believe any laptop RAM is available at the required speed yet.
