SW T&L vs. HW T&L
Well DirectX 7(Direct3D 7) was the first API to actually support Hardware T & L and when DirectX 8 came out, Shader Model 1 started with it. So I don't think there was any Shader Model Version 0.5 as you told. Not sure.
I think the GMA 3100 should support software Vertex Shader 2.0, but can't say about SW T & L. Even if it does support SW T&L, it won't emulate it properly and NecroVision requires Shader Model 3.0 to run properly. Software T&L is slower than Hardware T&L. Hardware T&L has a vertex cache which makes it much faster.
He can try using 3D-Analyze if he wishes and see any difference while launching the game.
