impossible to get 3-head setup

[rauldias]

HP Presario CQ62
ATI Radeon Mobility HD 5430
Mandriva Linux 2010.1 64bits
Xorg X11 7.5
X11-Server 1.7.7
fglrx 8.732

Everything works great.

Except that it seems impossible to get a Big Destop with 3 heads.

The notebook has 2 connectors: crt and hdmi.
There is 2 displays connected plus the notebook display, which I would like to
make it sit in the center.

So far All I could accomplish is a 2 head big desktop and the notebook display
to clone the first display.

So, is there a way for this?

The Videos Card spec says it should be possible to have a 4 head desktop.

I don't think Eyefinity support has been fully implemented in the Linux drivers yet.

exactly, triple-head doesn't work in fglrx yet, and it seems impossible to get any kind of official statement about that. (Probably because bridgman doesn't know, any those who do don't visit this forum.)
