Does NetBSD order the requests based on the disk geometry reported in
disklabel or has this code been removed (or did it ever exist in NetBSD)?

My guess is that this code could improve the performance quite a lot - if
the disks just had a geometry you could describe in disklabel.  (That is,
if you even _knew_ the real geometry..)
