Xorg Log output

Hi!
I use a Slackware current on a MSI S270 laptop, and recently upgraded the
Xserver to 1.4.0.90 and the ATI driver to 6.7.197. I also upgraded to a
self-compiled KDE4.
At first, when I started X, it seemed like two desktops were drawn on top of
the other, the one receiving the KDE taskbar seeming to use a 1024x768 output
while the LCD seems to display a 1280x800 screen underneath. Looking at the
Xorg.0.log file, I saw that both VGA-0 and LVDS were using the same monitor
entry in the xorg.conf. After googling and fiddling with xorg.conf options, I
finally managed to bind the VGA-0 output and the LVDS to a specific monitor
entry in the xorg.conf.
The problem is that apparently  the VGA-Output seems still to be considered
primary, and the LVDS secondary, as KDE still doesn't set the taskbar on the
Panel display.

It seems, according to the Xorg.0.log file, that the driver considers that
there is a VGA output (while no screen is actually attached) :

(II) RADEON(0): Added native panel mode: 1280x800
(II) RADEON(0): Total number of valid Screen mode(s) added: 0
(II) RADEON(0): Output VGA-0 connected
(II) RADEON(0): Output LVDS connected
(II) RADEON(0): Output S-video disconnected
(II) RADEON(0): Output VGA-0 using initial mode 1024x768
(II) RADEON(0): Output LVDS using initial mode 1280x800

And obviously, it sets up the resolution accordingly. It sets it up on Port 0,
which seems to determine it as the primary :

(II) RADEON(0): Output VGA-0 using monitor section VGA
(**) RADEON(0): Option "RightOf" "LCD"
(II) RADEON(0): I2C bus "MONID" initialized.
(II) RADEON(0): Output LVDS using monitor section LCD
(II) RADEON(0): Panel ID string: AU B121EW01 1280x800WXGA
(II) RADEON(0): Panel Size from BIOS: 1280x800
(II) RADEON(0): BIOS provided dividers will be used.
(WW) RADEON(0): LVDS Info:
XRes: 1280, YRes: 800, DotClock: 68900
HBlank: 128, HOverPlus: 8, HSyncWidth: 48
VBlank: 16, VOverPlus: 2, VSyncWidth: 3
(II) RADEON(0): Output S-video has no monitor section
(II) RADEON(0): Default TV standard: NTSC
(II) RADEON(0): TV standards supported by chip: NTSC 
(II) RADEON(0): Port0:
 Monitor   -- AUTO
 Connector -- VGA
 DAC Type  -- TVDAC/ExtDAC
 TMDS Type -- None
 DDC Type  -- MONID
(II) RADEON(0): Port1:
 Monitor   -- AUTO
 Connector -- Proprietary/LVDS
