The L2 cache is *on the CPU chip itself*. Any CPU recent enough to physically fit into an nForce board has the L2 cache on the CPU itself. I think the last Athlons to have separate L2 cache chips were the Slot A models, and even then, the L2 cache chips were still on the CPU module and not the motherboard.

Yeah, disabling the L2 cache on a modern CPU makes it really slow. But, it's still a useful troubleshooting option...
