Right. I thought it would be hard to see. But how much "not viewable" is
it? Are you using mplayer? Do you have many frame drops?

Can you test the 720p video with a lower clock? I'm interested to see
how low can its clock go while still watching the video. If you can
please use the following:
* the userspace governor (so that you can change the frequencies as you
please);
* try using powerprefs, if possible.

I have something in the back of my memory of Michel Dänzer saying the
memory consumption of DRI 1 a loooong time ago. This excluded my 8MB
Rage 128 M3, unless I used 16 bits per pixel (which, at the time, as a
side effect enabled DMA for XV, which was my main purpose, as I was
interested in playing DVDs with my iBook G3 600MHz).
OTOH, not too long ago, I reported that my Matrox G400 16MB wouldn't run
Ubuntu's compiz and the reply that I received back was that 16MB was too
little memory. :-/

The opportunity that I have is to purchase an iBook G4 800MHz. As I have
never used a machine with Altivec before, I don't know how it would be
useful for playing, say, DVDs with de-interlacing enabled or some MPEG-4
Part 2 or some H.264 videos.
Playing such videos would be the most "real time" demanding applications
that I would have. Others would be to compile things for Debian.

No, I don't play any games. I was just interested in knowing if the
hardware could cope with some things like avant-window-navigator (which
seems to need compositing).
Also, how is Airport Extreme working with the binary blob and current
kernels?

Unfortunately, my budget is limited. This is the reason why I would like
to know better before I actually get a ppc notebook (the primary reason
would be Debian development and getting Linux working on some ppc
boxes).
I'm also thinking of reviving gtkpbbuttons, pbbuttonsd etc, if I do get
a good laptop.
