This doesn't look right from my understanding of the d3d9 depth bias
behaviour. Afaik D3DRS_SLOPESCALEDEPTHBIAS is a multiplication factor
for the maximum depth slope (i.e. difference in z-value over distance
for a polygon's vertices), just like in OpenGL. I attached an
alternative patch to the bug.
