Gradients = banding = aaaargh!!!

Oke this is seriously driving me insane....
I am having problems with dark gradients and banding... It's Friday and I am tired and simply can't think straight in order to bug trag this problem.
I have a dell monitor 2405 and this model is not known to banding in general.
In Photoshop working with 8bit RGB images I can make almost any type of gradient and no banding is present. If I look really close I might be able to find something that could look like begining to banding, but I think that's down to the nature of LCD monitors in general... But I would call my gradients nice and smooth.
But in EVERY vector program that I have tried it's not possible to make a smooth grey gradient - I always get loads of stripes nad banding. If I copy a vector element and paste it into Photoshop i can see it's a grey scale image and hence it will also look banded in Photoshop.
I have tried with Fireworks, Illustrator and InkScape - they all behave identical meaning loads of banding.
Going from white to black = banding
Going from dark grey like #333 to black = banding
I have removed "quick render preview / options" and similar - but no help at all.
If Photoshop would show bad banding I would just say it's the monitor, but due to the fine gradients I tend to think it's something else.. Exporting from Photoshop via web optimize tend to give me banding again though
Is there someting obvious I should check?
Would looooove some help on this.
Thanks in advance.

I tried Fireworks 4 and Fireworks MX and created a created a quick gradient that is attached.
I just have the default settings and i exported as a 24 bit png I don't see any banding.

- Roland that image looks good to me... Thomas, you running 32bit display? Regarding 8bit, that will almost certainly result in banding as 8bit = 256 max colors, which is realy not enough, especially when viewed on a lcd monitor which can be kinda exacting when it comes to color boundaries.

Cheers both.. I feel I am getting mixed results in all this..
Roland your gradient does indeed look smooth on my monitor as well - how does these gradients look on yours?
Mines are def. showing some signs of banding:
Illustrator, FireWorks, InkScape and Photoshop

- in my limited experience you can't escape banding with 8bit.

Should not have mentioned the term 8bit
Everything is exported in 24bit png..

Could someone please make one or two gradients in png with the following colors:
#4C5866 --> #2C333B
#4C5866 --> #283524
For instance with the same dimensions as Roland posted.
