Thx for your comment. What about the following in vlVaDeriveImage:

-   w = align(surf->buffer->width, 2);
-   h = align(surf->buffer->height, 2);
+
+   alignment = screen->get_param(screen, PIPE_CAP_MIN_MAP_BUFFER_ALIGNMENT);
+   w = align(surf->buffer->width, alignment);
+   h = align(surf->buffer->height, alignment);

here

This is not entirely right but I feel it has more chance to succeed than the
current align 2. At least it works on my GFX6 card.
