Not quite. The fastest (and final) notebook to boot OS 9 directly was the 12" Aluminum PowerBook G4, 867mhz. I know because I owned one, and got a kick out of the fact that it was a little history-making computer.
Seriously, that thing would run OS 9 so fast it was unreal. I wish I had never sold it. And if you're looking to be budget-conscious, that particular Mac isn't a good choice because it's highly-sought after on the Bay.
