Really strange! Tested the patch against other games and it worked.
With NOLF2 I'm getting a crash too, but at a different location:
1 0x7e6217ca drawPrimitive+0x112a(iface=0xec7660, PrimitiveType=4,
NumPrimitives=18, numberOfVertices=20, StartIdx=0, idxSize=2,
idxData=0x3d871e0, minIndex=0)
[/home/klan/src/wine/dlls/wined3d/drawprim.c:540] in wined3d
(0x00000000)
0x7d2b3771: movl 0x0(%ecx),%edx
540 for (texture = 0; tmp_tex_mask; tmp_tex_mask >>= 1, ++texture)
