Is it possible to have a noise filtered effect similar to below, but have the white parts transparent?
My idea is to use this as a CSS background image overlay .png which would allow background colours to show through.

There is a method that pretty much allows you to do this without thinking at all:
Ctrl+Land bring the upper white arrow to the center enough, so that you will get white background ( Also, you might want to bring the top black arrow towards the center to make the black colors black ) ( This step is not necessary in this case ).
Edit > Define brush preset( Since the Brush tool was selected ), the created brush will straight away be selected.
Ctr+Nwithout the background color ( make it bigger than the original image, so you don't have to aim much ).
D( to default the foreground color to black ).
Image > Trim > Base on: Transparent pixels
It may seem like this has big amount of steps, but you can do this very, very fast.
For Transparent Noise
It is much better to use Fireworks. All you need to do

Another quick way to do it in Photoshop is to:
Filter > Noisefilter and set it as you like
Double-Clickthe (New) Layer or select
Blending Optionin the Layer Panel/menu
This Layer's white point value to around 213—222
Save for Web...PNG-24 with Transparency On
TIP: You can OPT+Click/ALT+Click on the white point to split it into a range
I built on Kerry's method, works great:
Voila! A layer with a mask which imitates noise
