openGl 1.4 for Radeon 7500??

Does anybody know where to find this openGl 1.4 updated driver to play knights of the old republic says that it is needed, but I can still play it without it, but I was wondering would it be much better with opengl 1.4, Thanks any reply would be greatly appreciated.

Since the 7500 doesnt support vertex or pixelshaders in hardware, it CANT support OpenGL V1.4 and no driver can fix that.
