ok, well this *clueless wanker* is Dr. Warren Hehre, developer of Spartan and numerous other scientific computing apps, who has been writing apps for MacOS for the past 20 years. i have a spiffy new 3.3 GHz 2010 Mac that came with SL 10.6.3 factory installed, and i also have the latest version of Spartan, which cannot access more than 2GB of RAM. he also told me that Apple *promises* that the next update of SL will actually allow 64-bit apps to access more than 2 GB of RAM. i believe 10.6.4 just became available, but i haven't had an opportunity to install it yet, as the computer is busy crunching numbers.
