Description of problem:
Displaying detailed partition statistics using "vmstat -p <partition>"
does not work on Fedora. This is due to new /proc/diskstats format.

Version-Release number of selected component (if applicable):
procps-3.2.7-21.fc10.i386

Steps to Reproduce:
# grep sda1 /proc/diskstats
   8    1 sda1 33 629 1328 117 0 0 0 0 0 117 117
# vmstat -p /dev/sda1

Actual results:
Partition was not found

Expected results:
sda1          reads   read sectors  writes    requested writes
                 33       1328        0           0
