Peter,
I'm not sure I can help with your specific problem, but I can tell you what I do.
I've built all my special cursors from png files, packed them up with img2py, then load them into cursors with wx.CursorFromImage(). I ended up using 16x16 images for the Mac, and 24x24 for Windows and GTK -- I can't really remember why, though

Now I'm left with 2 cursors: one is an empty open hand and one is a closed hand.
I've got versions of both of those -- they are in wx.lib.floatcanvas, if you're interested.

Here there are.
I have no idea why I got that invalid Image. I tried saving it with both Photoshop and IrfanView, no success. In the end I become enlightened, loaded the old cursor files as images, extracted a 16x16 sub -image from them and created the cursor for OS X from that image.

I get a “Bus Error” when trying to load a 16x16 PNG using
wx.CursorFromImage(wx.Image(“images/hand_up.png”))
Is this expected behavior ?
Sure. That’s not what you wanted?
A bus error is by definition a bug, but I"d first try to make sure that your wx.Image is valid, so you can see if the error is in reading your png or in making a cursor from it.
P.S. I will look at floatcanvas cursors, I just wanted to try and use mine.
No problem. They aren’t that special – if you show me yours, maybe I’ll want to use them!
