I have a procedural node based material in blender that produces areas of two colours, black and white. Can I use geometry nodes to scatter points only where the material is white? I'm looking to get the effect of weight painting, but using a procedural material. Is this currently possible?

It's not possible to transfer data from the material to geometry nodes. Currently the data flows only in one way : Geometry Nodes Attributes > Material.
I don't think there is a plan to support this feature in the future.
You can however bake the textures and use the Attribute Sample Texture node to achieve the result, but you will lose the procedural aspect of the workflow.
You may be able to plug into the data flow if you use OSL but that requires good programming knowledge and restricts rendering to CPU only and Cycles engine only.
