I took it upon myself to install 3.0.2 in a vm on VMware Workstation 6 on my local workstation so I can get the build numbers myself. I don't know if this info is useful to anyone else but here are the updates and the associated build numbers for them.
3.0.2 Update 1 --> 61618
November 15, 2007 Update --> 62488
November 30, 2007 Update --> 63195
January 2, 2008 --> 66399
