Generally, unfortunately, this doesn't work. As of froyo, if it is a signature permission, it will work -- the original app will be granted the permission once it is known. (This is safe because it is not a permission the user ever needs to be shown anyway.)
But for a permission the user needs to approve... it won't get granted until the first app is re-installed or updated, and the permission it wants is known. This is something that really needs to be improved.
