Their current public LDK contains their bootloader and a 2.6.32 kernel
(and they're still using machine ID 3333 in that one). They have
started upstreaming their u-boot port, but I don't what the plans are
on what the LDK will use in the future.

Will the nvidia atags ever be used in the kernel? If not, it'd make
more sense to have the warning there so that the bootloader is fixed
than having the no-op stub.
