Is this still a problem with the Cairo based renderer? I see some banding but I have to really look for it. Others might be more sensitive. (Could depend on display and operating system too. I'm using LInux)

I tried making gradients in Gimp with and without the dithering option. If I look very carefully I see banding in both cases at about the same level.

If it is still a problem I see two ways of dealing with it:

1. Add a dithering filter to Inkscape as already proposed.

2. Add code to optionally dither gradients when either rendering on screen or generating a PNG. We rely on Cairo to generate the gradient so the approach I would take is to blend in a small amount of noise.

I've tried both methods and while I can see a small difference it's hard see that it is really helping the bandingay
