that's what I'm doing too, but if you have a closer look at the logs in Console, then you get a message saying :

2001-10-03 13:45:14.614 Solitude[818] Warning: TIFF image with unknown extra samples assumed to have unassociated alpha. RGB values have been premultiplied

So now another question is : "how to make this new channel a *real* alpha channel recognized by the system?"

You need to perform the following command in the Terminal:

tiffutil -cat YourFile -out YourFile

The best solution being to create a droplet for this: using the DropScript utility available in the Darwin Repository
