And then you need to run 'sysctl -p' (of course, settings will take
effect on the next boot too). Or you can set the option manually  with:

sysctl -w vm.laptop_mode=1

BTW, Mandrake 9.2 includes this patch (not enabled by default of
course), and if installation detects a laptop, noatime is set (at least
on ext3.
