Not all parts of the MIPS64/Linux kernel are 64-bit clean when it comes to addressing. There used to be troubles with 64-bit tools until recently, too. That's why the kernel is built with 32-bit addressing and only after the final link converted to a 64-bit object to satisfy firmware that needs such for a load. It should be fixed one day, but that's not necessarily a starter's task. -- + Maciej W.
