Comment(by andy):

 Balaji knows how to fix half of this already anyway, he says XGlamo is
 using the wrong /sys path.  On current kernels it needs to be

 /sys/bus/spi/devices/spi2.0/state

 If you do the xrandr, and on a terminal do

 export DISPLAY=:0 ; echo qvga-normal > /sys/bus/spi/devices/spi2.0/state

 it will correct the bad display into good QVGA.

 The remaining problem is after framebuffer blanking, you'll get a WSOD.
