Does the spherical mapping work fine with ATI?
(I mean the flag 64 for textures).

Yes it does. My game ( Kick Shot Pool ) originally used cubemap texture layer 1 for cards which support it. A number of ATI cards ( with a range of the latest drivers, so not driver problems ) saw nothing. When I replaced the cubemap with a sphere map, the problem was gone. I changed no code, so you won't have any problems if you stick with sphere maps.
This does appear to be a bug.
