The only one I've seen is JS overclock 1.0 But, its not really that good

Yeah i used to use JS when i had my toshiba e310... first of all it only overclocks the 206 mhz proc to like 236, and also it isnt sticky, so every time you turn off the device it goes back to the stock speed. The reason overclocking is so much more common with x-scale processors is because that's what the name x-scale means, scaleable, as in it is designed for the speed to be changed.
