Introduction to the Shuttle X50 ( http://au.shuttle.com/product_detail.jsp?PI=1241 ) is with this specs:

PROCESSOR Intel Atom 330 CPU
CHIPSET Intel 945GC + ICH7
VGA Intel GMA 950 256bit 3D engine with a powerful 400MHz core and DirectX 9 3D hardware acceleration
Dynamic Video Memory Technology(DVMT)3.0 supports up to 224MB of Video memory
AUDIO Realtek ALC662 5.1 Channel High Definition audio
ETHERNET RTL8111C 10MB/s,100MB/s,1GB/s
LCD Panel 15.6" 16:9 Wide Panel, 1366 x 768 pixels

all seem nice to install macos on it.

I could install 10.6.5 using PC EFI method without any problem ( PC EFI 10.6, DSDT modified with DSDTEditor, custom atom kernel). I could run the system with VESA mode. But if I patch my DSDT file i could active my GMA 950 card (device ID: 0x2772), but my internal screen isn't recognize. I could connect only an external screen.... So to see more, I have activated the remote manager then when I don't connect external screen , I could take a look the screen property( see the screen shot)

Since severals days i try to be able to use my build-in screen but without any success.
May you help me ?

See my DSDT for my video:
