Ok, I saved particles with color, then loaded them without color, so the color is evaluated over again. The color updates, but the opacity does not. Just to check, I inverted the opacity map, and nothing changed on my render. I switch back to Render Scene Particles and the opacity is indeed inverted.
Oh and could we get a progress bar on the setting particle colors? I had no idea it would take so long…

I am getting mixed results, depending on my particle color setting, but I am generally able to get my opacity to work. Here is what I am seeing in my tests with Load Particle Colors off and Scale Density using Material Opacity selected.
With Custom Particle Color, I get particles matching my Custom Color swatch, but no density scaling.
With Material Self-Illumination, I get no particle color and no density scaling. (This seems odd at first, but might actually be as designed, in order to avoid re-evaluating the particle system.)
With Custom Material Self-Illumination, I get particle colors matching the self-illumination channel of the selected material, and density scaled by the opacity channel of the same material. This is working as I would expect.
I will dig into this issue a little more to see if I can nail down specific failures. (It would be helpful to know exactly how YOUR color and opacity settings are configured.)
My suspicion is that certain combinations should be disabled when loading from file, but in the current build you are allowed to choose material settings that yield improper results.

There seems to be a bug here. When using Custom Particle Color, I do see a progress bar during "setting the colors." However, when I switch to "Custom Material Self-Illumination" the progress bar shows nothing.
With Custom Material Self-Illumination, I get particle colors matching the
self-illumination channel of the selected material, and density scaled by
the opacity channel of the same material. This is working as I would
expect. <<
Ah hah! I have reproduced the failure and will log the defect.
