I was thinking of just a "void **priv" array in the ggi_visual, and we
hardcode certain index values to certain libraries, like 0 is always
display, 1 is always helper, 2 is always ramdac...  But we might as well
just do what you've done, have display_priv, helper_priv, ramdac_priv
etc...  I'd say stick with that unless someone has a bright idea.

OK, I'll get on it.
