unwrap preserving texture

Hi forum.

So I have this scanned 3d model. The scanner outputs a colored point cloud, and with a few steps in meshlab I'm converting the point cloud to a mesh and applying color data to build a texture map.

It's all cool, output is a nice textured mesh, but the resulting uv map is an utter mess. Something like this example, only a lot more complex: http://bit.ly/Z2r6Uj

This makes it impossible to touch-up the texture, so what I'm looking to do now is mark proper seams and unwrap, but I need the texture to be rebuilt in the process so that the model looks the same and I can afterwards fine-tune what requires it.

Any ideas, regardless of the software needed? (I'm a Blender user but whatever)
