"As we speak I’m downgrading the Snow Leopard partition on my trusty old Core Duo 2006 MacBook Pro back to Leopard"
Those early MacBooks had 32-bit CPUs. Wonder if Snow Leopard was problematic on those, since that's when Apple started the transition to 64-bit, finalizing in Lion. Would still be bad if this were the reason, but might also explain why other people had a better experience.
