I can. Do you want to check it out yourself? That will be great. On the other hand, if you are looking to check out some thing different quickly, As I said earlier, I have not done any great deal of changes. Just checkout the head and alter a few parameters in the /sys/mips/conf file according to your hardware and compile. It just works !!!
