Ok, well you don' t need to run special software. You just need to use a 
non-optimized VM 
The *worst* case is turn 32bit mode on, and use Rosetta
I've put a non-optimized VM in the experimental folder/COCOA 
via 
http://smalltalkconsulting.com/squeak.html
called 
Squeak V5 SLOW VERSION FOR TESTING DO NOT USE FOR GENERAL USE.app.zip
That gives you something that is like 8 or 10 times slower than normal.

Perhaps someone can run some benchmarks other than tinybenchmarks to confirm?
