Make sure you clamp your values.

The second code sample looks good except this line which doesn’t make much sense:
float3 result = N + (uv.x * xGrad) + (uv.y * yGrad);
Why would you add scalars to N which is float3?

Should be more something like this:
float3 result = N + float3(xGrad,yGrad,0);
return normalize(result);

I’ve been using the same maths when generating normals from a height map in a UDK material,
