That looks like they might be reset by pm-utils. See

pm-utils (1.4.1-15) unstable; urgency=medium

  * laptop-mode: If there is no state file (such as at boot), don't overwrite
    /proc/sys/vm/ values with fixed kernel defaults, simply do nothing. This
    allows sysctl.conf to set these values. Thanks to Osamu Aoki!
    (Closes: #659260)
  * Add 17-fix-wireless-hook.patch: Fix typo in wireless hook to make enabled
    check actually work. Thanks to Whoopie! (LP: #1299975)

If you run
touch /etc/pm/power.d/laptop-mode
and reboot, is the sysfs value correctly set?
