This is awesome news thanks for the info.

Does this fix the 3d acceleration or do we still need the patch?

Cool. Why stop there!? Do as much as you can with it. DF2 should get more love! :D

I am still having issues with 3D acceleration support. Despite following certain "fixes", the screen is still black. And certain Force Powers do not work as they should have been in '97 version.

I'm sorry, I'm not affiliated to GOG or the publisher, nor do I have the game (just posted the changelog), so can't help you in any way other than suggest to contact GOG Support.

Thanks bro. I did try it and worked like a charm. The Force power problem still persist though. :/
Basically, in Multiplayer, I no longer can use Force Blindning, Throw and Deadly Sight regardless of how much force powers I have left. But Protection I can. And I don't understand why.
