The maple platform failed to load because it's firmware could not take a
link address of 0x4000000. A new platform type with a link address of
0x400000 had to be created for the maple.

Without this patch the firmware loader says it is unable to parse the
ELF header and dies. This patch lets 2.6.31 boot without issue. At
the current head of k.org git, at least with an NFS mount, I'm getting:
Kernel panic - not syncing: No init found
So I'm not sure what the deal is there, but this patch is still required
to get the firmware to load the kernel.
