I have Wince 6.0 with mini6410 BSP. Try to creat a portrait orient screen. At Platform Builder, I changed the platform.reg file under "SMDK6410\parameter files" node. I change the value of Rotation to 90 degree. After built an image and bring up the WinCE, the screen looks like the old one(landscape screen). Does the driver support screen rotation for mini6410?
