In a nutshell:
  • 10.3 has support for more than 4 GB of physical memory addressable by the OS (but not my individual processes)
  • 10.4 has support for 64-bit processing in non-GUI processes
  • 10.5 has support for 64-bit processing in Cocoa GUI applications
Two more:

10.2.7 (G5-only) had a 64-bit version of Accelerate.framework, i.e. for AltiVec (math and vector processing).
And 10.6 has a 64-bit kernel (alongside a 32-bit one), and therefore support for 64-bit kernel extensions.
