Hi Frederico, wait-IO is another CPU state in addition to user, system, idle. It was added in kernel 2.6.x and is present in some Redhat kernels. Before that it was probably counted as "idle" or "system". That is a kind of philosophical question :-)
The patch will touch linux.c, metrics.h and key-metrics.h. I also made some changes to the web-frontend to show the metrics in the CPU-Report. All of this is already in the main branch. Wait-IO is also present in some other unixes. To answer your last e-mail: I am fine with holding it back for 2.5.8.
