I was able to run the demo on my Netbook (Advent 4214, 1 gig Ram) with 3dAnalyze, but it took a bit of fiddling with the options. Under DirectX 8.1 and 9.0 options I ticked 'force SW TnL', force wbuffer (an odd one, when you run it it says wbuffer not supported, using zbuffer, but if you tick zbuffer instead it doesn't work), and 'force anisotropic filtering.
It runs fine at 800x600 with the details low - turning on bump mapping turns everything white, and I didn't try turning on high detail textures, shadows, water reflections, and so on.
This is just for the demo, but I expect the same would work for the full game.
