Have a look in the README file for the cedartrail BSP. At the bottom you will find:

Work Around for VGA and LVDS Display issue in PVR driver
--------------------------------------------------------

The PVR driver has a issue that for some systems it causes
it to incorrectly assume that a LVDS display is connected
while infact a VGA display is connected and Vice Versa.
If your VGA or LVDS display does not work with
"cedartrail" MACHINE, then if you have connected a VGA display,
add the following to the kernel command line:

video=LVDS-1:d video=VGA-1:e

<snip>

I suspect it's this. Watch out if you use HDMI as well - the VGA fix seems to break HDMI. On my systems the VGA then works, but the HDMI pauses a lot running the same image! I think you can use similar magic for HDMI (or did I just take it out?).
