Dual screen problem

[Moritz Lutz]

Hi everybody,
i got the a problem with dual screen mode. I own a intel945GM with a dvi and
a vga port, now i bought a second graphik card a ATI 7000 Sapphire DVI to
get the 2 monitors working both with dvi. But i got a problem only the
onboard chip is starting (i810) and the screen on the PCI is black.

Here is my config:

And here is the xorg.log

(WW) RADEON: No matching Device section for instance (BusID PCI:4:4:0) found
(EE) Screen 1 deleted because of no matching config section.
(**) RADEON(1): RADEONFreeScreen

but lspci | grep VGA told me this:

00:02.0 VGA compatible controller: Intel Corporation Mobile 945GM/GMS/940GML
Express Integrated Graphics Controller (rev 03)
04:04.0 VGA compatible controller: ATI Technologies Inc Radeon RV100 QY
[Radeon 7000/VE]

Maybe someone can help me.

Greetings
