In the pasts partitions did not have the same counters as disks. So it was 
very easy to ignore partitions: remove all devices that have no (or zero) 
counters.

Apparently we finally have counters for partitions, so I guess we'll have 
to look at another way to get rid of the partitions ;-) Care to send me 
the output of /proc/diskstats ?

It will not be easy to make the distinction unless I assume that only 
certain block devices that are enumerated are partitions (eg. sda1, hda2) 
but not others (eg. ram1, md1).

Thanks for reporting !
