I often use the stack pointer for storage in a tight kernel (using TSX/TXS). It's handy when you need to save the value of X temporarily, and can often shave off a few cycles. Just make sure that if you use the stack in your program, that you save the stack pointer value beforehand and restore it afterwards.
