It's a pity. I love watching DivX movies on TV.

I only tried mirroring. There's nothing to add in XF86Config-4. I
booted MacOS X with the external monitor connected. Then reboot in
order to start linux. That's all. Take a look at XFree86's log: it
detects both monitors and the correct modelines for each one (at least
for a recent monitor). I got 1024x768@85 on the external monitor
automatically. Same for TV but, in this case, I don't see nothing on
TV (I guess we need extra information from ATI in order to include
TV-Output support into framebuffer's driver)
I also tried the aforementioned trick (instead of booting MacOS X):
1. Plug the external monitor to the iBook.
1. Turn on the iBook and inmediately close the lid.
2. Open the lid once the first frame has been displayed on the external
monitor.
It didn't work. Maybe because I was using a very old monitor when I
tried this (no EDID information available, etc...)
