Speaking of multihead. Have anyone managed to get mulihead working on a
Powerbook 15" with a radeon 9600 card?

I've tried both XFree86 4.4rc1 and the xserver-xfree86-dri-trunk package.
It (xinerama) almost works but the dvi-output is distorted.
The external monitor seems to have the same distortions as these pictures:

Do you hvae "UseFBDev" enabled ? You shouldn't for multihead...
No, I use this configuration:

If I remember correctly the output on the DVI connection might look like the picture
I got when I tried to get XFree86 to work with a 2.4 kernel.

It is hard to describe how the screen looks like but:
It looks like the framebuffer isn't sent by the ramdac in a linear fashion. The screen gets divided into tiles of the 32x32 pixels or something. If a small window (xlogo) is placed in the top left corner I see parts of the window scattered all the way to right hand side of
the screen.
The cursor is drawn ok though but I guess it is because it's a hardware cursor.

If I look at the monitor before starting X I see some text from the kernel boot. It looks like the text the kernel prints just as it starts booting (initializing radeondb). This is
displayed without the "effect" I tried to describe above.
