Comment(by Quozl):

 The systems that do not boot have 1 GB of memory, the systems that do have
 512 MB of memory.

 Restricting the ramdisk and device tree addresses below the 512 MB border
 appears to fix it, though we have no idea why the Linux kernel
 implementation is so picky about it.

 Fixed in svn 3051 by moving ''load-base'' and using that as the upper
 bound for the ramdisk.
