In RHEL4 iostat displayed statistics per NFS mount, can this functionality be reproduced in future versions of RHEL?

Issue

On Red Hat Enterprise Linux 4, the iostat output shows statistics per NFS mount:

nlvdhs10-odb:/vol/oraacc301/ora_db_ehracc         0.00         0.00         0.00         0.00        57.60         0.00

While on Red Hat Enterprise Linux 5, the numbers are per volume on the NFS server side:

What is the reasoning for this and is there a way to reproduce the Red Hat Enterprise Linux 4 behavior in Red Hat Enterprise Linux 5?
