Karl,
The man page of atop has these words
Disk load is shown if per process "storage accounting" is active in
the kernel or if the kernel patch 'cnt' has been installed.
But to me, it seems to come with everything. I tried the simplest
(i.e. default) installation on my Red Hat 4 box. Everything seems to
work.
But I wish it did less. When I cleanup after my trial, I have to
use chkconfig to prevent it from running as a service at multiple
runlevels. And it stores its result in /var/log and config in /etc/atop,
etc.
