Would be interesting to run

	blockdev --setra 1024 /dev/hdXX

here.  We're getting more idle time with 2.5 and that can only
be due to disk wait - the IO scheduler changes.  This might make a
small difference.

Well that code is still there.  I'd expect a very small benefit from it
in this testing.
