I should probably point out that ibuffer already has a process column,
and if it didn't it would be easy to define it oneself:

(define-ibuffer-column process ()
  (ibuffer-aif (get-buffer-process buffer)
      (format "(%s %s)" it (process-status it))

Then put `process' anywhere in your `ibuffer-formats'.  
I personally use:

(setq ibuffer-formats '((mark modified read-only " " (name 16 16 :left :elide) 
" "
                                (size 6 -1 :right) " "
                                (mode 16 16 :center :elide)
                                " " (process 8 -1) " " filename)
                          (mark " " (name 16 -1) " " filename)))

This displays the process entry right before the filename.
