Please try to set on/off of DOVEFB_SINGLE_DISPLAY_ACCURATE_PCLK in kernel configuration to see if it helps. Thanks.

Bug description:
The dove kernel's video output has broken with the most recent kernel uploads, causing my monitor to go into "Unable to display video mode" when using a newer kernel. This change seems to be related to "DOVEFB_DISPLAY_MODE=y" - which has not been set with previous Dove kernels which did have working video output.

The following command line has been used for video output: console=ttyS0,115200 console=tty0 mem=512M video=dovefb:lcd0:1280x768-24@60,lcd1:1024x768-16@60 clcd.lcd0_enable=0 clcd.lcd1_enable=1
