I would not have high hopes of DOS2 working under wine. If I recall correctly, DOS1 EE was DirectX 11 only, so I assume DOS2 is too. And DX10/DX11 support in wine is still work in progress.
I'll definitely give it a try once it comes to GOG, but I too was betting on a Linux port when joining in the Kickstarter. Hope I'll win ;-). Otherwise, I can at least drown my sorrow in style with the dwarven ale mug.
