 [ I hope it is appropriate to use docs.openmoko.org for Xorg driver bugs
 even though openmoko inc. is not shipping it yet. ]

 Steps to reproduce:
 1) xrandr --output LCD --mode 240x320

 Expected results:
 1) X switches to 240x320

 Actual results:
 1) X switches to 240x320 but bottom of the screen is shown at top of the
 screen. As if the hardware was doing "(y + 30) % 320" before putting the
 pixel to screen. I also see odd horizontal lines which are somewhat
 difficult to describe without a photo (I'll try to provide one later). Do
 you have some preferred test images?

 More info:
 1) kernel is from andy-tracking b8b36e5ec3db71d5
 2) X is from debian experimental, xserver-xorg-core 2:1.5.99.902-1
 3) xf86-video-glamo is 703acea13
