Interesting, any idea why they didn't use the internal TMDS even for
single link?

Thanks.

So basically, it looks like:

PowerBook5,*:		'powerbook-exttmds'
PowerBook3,[45]:	'powerbook-inttmds'


What about PowerBook3,3 (I forgot that didn't have DVI yet...)? I wonder
if that works with "ibook" or has a different setup for VGA and S-video.
Presumably the latter, as in contrast to iBooks they're separate
connectors.
