Hello. 
I successfully loaded DL xorg driver to my ubuntu 9.04 jaunty with Samsung SyncMatser U70 800x480. 

I prove framebuffer problem modify fb device from /dev/fb0 to /dev/fb1 
(/dev/fb0 is framebuffer of VESA 2.0 compatible VGA (Radeon 9200) and /dev/fb1 is from udlfb) 

but, there is color-broken problem. I think Xorg server can't recognize proper color depth of monitor (16bpp) seeing last line of next log message. 

------------X.org.log--------------- 
(II) DL(0): EDID vendor "SAM", prod id 951 
(II) DL(0): Using hsync ranges from config file 
(II) DL(0): Using vrefresh ranges from config file 
(II) DL(0): Printing DDC gathered Modelines: 
(II) DL(0): Modeline "800x480"x0.0 33.00 800 840 968 1056 480 481 484 505 +hsync +vsync (31.2 kHz) 
------------------------------------- 

I link photo reveals symptom of color problem in gnome (due to 40KB upload limit) and attach full X.org.0.log fragment about DisplayLink Device.
