So, the lapping experiment is done, mobo still works, and I gained some knowledge. First and worsest of all, there is NO heatspreader inside of the nForce2 chip in these later revisions with completely plastic chip - unbeliably as it sounds, but true for the nForce2 SSP Ultra 400 in my case.
Let pictures speak for themselves:

Unfortunately nVidia showed me again what I would call "nonsense" at best.
Testing lapping (pictured) was on JetWay N2PAP Ultra. I dubt the mobo will work, but it was dead one for sure before, so... (two caps in the Vdimm powering explode and took the mosfet with them...)
The chip thickness (measured over the green bottom) is exactly 1.25 mm.
When I reach 0.475 mm the resistor at one end and then these wires begin to surface - so, I lapped my DFI LP B nForce2 core to 0.50 mm and I hope for highly increased overclocking of the chipset
When I get there a good heatsink, we see
