Socket S1 is apparently physically identical across all four of its revisions- S1, S1r2, S1r3, S1r4. The differences lie with the specifications of the buses that connect to the socket. For example, S1g4 uses DDR3 while the others are DDR2. The original Socket S1 is limited to an 800 MHz HT2 link speed, while the others are 2 GHz+ HT3. I am not 100% sure about the differences between S1g2 and S1g3, but I do know that the S1g3 units are K10-based while the S1g2 units are K8-based. I think that the difference may be in the power planes of the sockets, since both S1g2 and S1g3 support DDR2 and HT3. I would guess that the ZM-84 would work unless Gateway didn't include BIOS code for the K8-based S1g2 chips, but I can't guarantee that. AMD is a little behind in publishing information on Socket S1 to their website, so I can't say for sure if it is in fact compatible or not.
