The difference is in the speed that the HyperTransport runs. On the ZM-86, it runs at 1800MHz, on the ZM-87 it runs at 2200MHz. In theory, this means that the interconnection between the processor and the North Bridge / South Bridge can run much faster. This could, in theory, make the SATA controller, Firewire controller, etc. be less bandwidth-limited. In a laptop, that's probably not an issue, and certainly not worth the premium you're going to pay.
