Desktop Spanning on ze4229, secondary monitor not detected

Here's what I've got:
  1. Kernel 2.6.11-1.27_FC3
  2. Fedora Core 3
  3. Xorg 6.8.2
  4. ATI Mobility Radeon IGP 340M
  5. Secondary monitor is a HYUNDAI ImageQuest L72D
  6. Pavilion ze4229 notebook

Tried so far:
  1. I've tried to use the GUI interface to tweak parameters
  2. I've manually edited the Xorg.conf file tweaking a couple things

I cannot get this thing to span the desktop across two monitors. However, it does display a cloned image on both monitors by just plugging it into the notebook, but of course I'm trying to improve my productivity by using multiple monitors instead of ALT+TAB switching all the time.

Now for the diagnosis:

I found this in the Xorg logfile:
(WW) RADEON(0): Failed to detect secondary monitor, MergedFB/Clone mode disabled
.
.
(a few seconds in time pass and millions of poor little electrons get churned up in circuit land)
.
.
(**) RADEON(0): Using AGP 4x mode
(**) RADEON(0): Enabling AGP Fast Write
(II) RADEON(0): Depth moves disabled by default
(II) Loading sub module "shadowfb"
(II) LoadModule: "shadowfb"
(II) Loading /usr/X11R6/lib/modules/libshadowfb.a
(II) Module shadowfb: vendor="X.Org Foundation"
compiled for 6.8.2, module version = 1.0.0
ABI class: X.Org ANSI C Emulation, version 0.2
(II) RADEON(0): Page flipping enabled
(!!) RADEON(0): For information on using the multimedia capabilities
of this adapter, please see http://gatos.sf.net.
(II) RADEON(1): MMIO registers at 0xd0300000
(WW) RADEON(1): Only one monitor detected, Second screen will NOT be created
(II) UnloadModule: "ati"
(II) UnloadModule: "radeon"


Any ideas?
