I've been thinking about that one as well... It's the main remaining culprit.

That's not a very good idea, since it's Mac only.

You cannot do everything in fb_find_mode() since monitor sense is a per-monitor
issue, not global.

One possible thing (in each fbdev driver :-(

    default_mode = NULL;
#ifdef CONFIG_PPC_ALL
    sense = ...;
    default_mode = mac_map_monitor_sense(sense);
#endif
    ... = fb_find_mode(..., default_mode, ...);

Or: should it be considered as a real mode_option (if mode_option == NULL)
instead of a default mode?

I'm dragging this to linuxppc-dev, for input from other Mac guys, and to
linux-fbdev.

Gr{oetje,eeting}s,
