Following patch adds support for suspend/resume functions. I had to change the get_cbmem_toc because macro magic did not work well.
The writes to NVRAM are not used in asrock board (k8 pre rev f) but they should work when used with am2 boards. In fact maybe the suspend will work on mahogany or others ;) - with some simple patch which follows for asrock.
