I like this idea alot. I can only hope that the adapter will not cover the 478 mounting holes. I've seen benchmarks indicating that a pentium M overclocked to 2.5ghz is comparable to an A64 4000+ at stock speeds. I should mention that the pentium M had the deficit of an 855 chipset compared to an nForce3.
