A gradient fill is in many respects a blend.
It is the darker colours that show the bands in the mid tone regions the most so why not break your screen area up into 3 separate areas. Then by using named colours in your gradient you then can make your gradient a lot smoother in your 3 separated areas. Also use the blend tool to get your palette for your named colours
It's amazing that this causes such a problem. I've encountered it myself and it requires serious thought if you really want to hide the banding. Clients spot it straight away. I tend to do large graduated fills restrained to one colour in Photoshop.
@Xara: Is there really a serious technical reason this cannot be overcome in a future update/upgrade?
I should think a Blend of 999 steps should be enough for most.

This, screen representation, is where CorelDraws being able to set the number of steps of a gradient comes in handy. Doesn't change the PostScript output, but it does a good job for exporting bitmaps.
How about creating a a large multi step blend?
