As previously requested.
The following is the behaviour of the latest mainline kernel on the LDP3430
platform.

<spontaneous reboot>
My guess is it's the watchdog which hwmod apparantly can't deal with.
Note also LDP framebuffer doesn't appear to work in this configuration:

With the FB_OMAP driver, it looks like the screen isn't being correctly
driven - the openhand logo appears in outline with green splodges in
places (but unfortunately, because of the reboot, it doesn't stay there
for long enough to get a photo of it.)
