As far as I know, the driver is not lying.

What you're currently facing is the so-called "Clone" mode i.e. both screens show the same desktop (I know that you already know what clone mode is ;) ). Therefore both screens are at (0,0)

Clone mode is what you get when you type:
"xrandr --output VGA --auto"

If you want to get independent screens (Xinerama style) you will have to type:
"xrandr --output VGA --auto" (just to turn on the monitor)

"xrandr --output LVDS --right-of VGA" (just make sure the framebuffer is enough to contain both screens, if not you will have to set the virtual resolution in your xorg.conf)

In this way you will get:

LVDS 1024x768+1280+0 and VGA 1280x1024+0+0 (at least in theory).

In the case of Clone mode Plasma should be able to shrink the desktop to the exact resolution of the screen. Each screen show the same desktop with different resolutions. The result is even uglier in GTK (since the bottom and bottom-left parts of the screen are not hooked correctly).
