[Openchrome-users] Dual monitor possible with Openchrome and VN800 chipset?

[Rollo]

Hello everyone! I'm trying to integrate an external monitor into the desktop
of my laptop, which runs a Via VN800 chipset and Openchrome driver on Debian
Lenny.

Any ideas on how? I have tried Xinerama mode in xorg.conf, adding a second
"Device" with the same "Busid". But X refuses to start ("Fatal server
error: Requested Entity already in use!"). Would really appreciate advice.

Here's the hardware:

# lspci | grep VGA
01:00.0 VGA compatible controller: VIA Technologies, Inc. CN700/P4M800
Pro/P4M800 CE/VN800 [S3 UniChrome Pro] (rev 01)

And the functioning xorg.conf (extract):
