Got almost the same laptop, the onkyo dx which has a bit higher res screens, 1366x768 with a similar problem. the bottom screen (right in the expanded configuration) does not come on (no back-lighting).
i'm running arch64 with the following relevant packages:
stock kernel 2.6.32.7
glproto-git 20100206-1
libdrm-git 20100206-1
xf86-video-vesa 2.2.1-1
xorg-res-utils 1.0.3-3
xorg-server 1.7.4.901-1
xorg-server-utils 7.5-3
xorg-utils 7.5-1
xorg-xinit 1.2.0-1
xf86-video-fbdev 0.4.1-2
xf86-video-vesa 2.2.1-1
xf86-video-ati-git 20100206-1
i used the same xorg.conf with the following mods:
1) radeon driver instead of radeon
2) 2732x768 virtual screen size
after running startx, the LVDS screen is fine (although glxgears indicates only about ~570 fps, that's a problem for another day). i then physically extend the screens and run xrandr:
xrandr --output LVDS --auto --output DVI-0 --auto --right-of LVDS
as far a x-server goes, it looks like everything is good, the desktop is extended, the mouse pointer moves properly off-screen, but the screen is not lit.
the X.log can be found:

Any pointers, suggestions or other requests for other info is greatly appreciated!
