You'd still have to emulate a Malta guest at the moment. Getting it to work on the Ingenic XBurst cores required a little effort in the kernel due to slight incompatibilities with the MIPS32r2 spec, so its possible there'll be problems with Loongson too. I presume Loongson may use highmem, if so you'll want to disable it. I still need to get those patches sorted out. Let us know how it goes or if you hit problems!
