i guess the problem is that as disk controllers got more
intelligent, much of the statistics that were collected
by the kernel couldn't be directly measured.  the result
is the implementers chose not to provide any measurements.

one could provide approximations though.  or do any of the
disk interface specs (st506, esdi, scsi, etc) provide for
obtaining performance measures directly from the controller?
if they do, i could push for getting these measures in.
