OK, i tried it and... it worked. I'm currently playing the game and so far, everything works pretty fine - except a mouse-lag, if you're inside some menus or have conversations. This can be fixed though, if you disable directDraw within "dxdiag", but in exchange, this will also make the camera turn too fast, if you hit the borders with the mouse-cursor, so it's not the best workaround.
I'll upload the modified german EXE to patches-scrolls.de. Will do the same with the international CD and DVD-Patch.
I think someone mentioned it before somewhere, but just in case: If you got audio problems (sound and music skipping), then you'll have to reduce the sound-hardware-acceleration to "basic".
EDIT:
Since i don't get a response from the patches-scrolls staff, i uploaded the patches to 4shared and i'll post the links to them here:
