Correct, the CLUT modes are not supported by the driver (and, if I recall right, never has). The CLUT modes are quite simple in principle, but I think there are quite many corner cases that need to be handled when using CLUT modes (related to scaling, and things like that). So it might be quite straightforward to hack it in, but more work is probably needed to make it reliable. Tomi
