(Get the code!)
I need to second this request. Being able to view disk i/o stats per process is very important as it would greatly help newbies, advanced users and developers alike to track down what i/o hogging processes are causing their ubuntu systems to slow down. This happens more than people think, the recent spate of bugs/forum posts related to trackerd is just one example of how top/vmstat/iostat et al are useless for such a task.
People are asking for this capability all the time, see

as just some examples of users screaming for this functionality. While I'm an avid Ubuntu user myself (I completely wiped my M$ Windoze partition btw) I think it's pretty sad that all other OS's have that capability built-in but ubuntu doesn't, and all it takes to fix is to turn on a simple kernel config option...
BTW, I got alerted to this by an excellent thread on linuxquestions

which mentions that the latest version of collectl also supporting the "new" i/o /proc interface (not in the repos yet, see bug# 135037)
