I can see at least two problems with this:

1. /usr/lib/pm-utils/power.d/95hdparm-apm checks for the presence of /var/run/laptop-mode-tools/enabled , and when found, the pm-utils hook immediately exits because it assumes laptop-mode-tools is managing HDD PM (by checking for CONTROL_HD_POWERMGMT in /etc/laptop-mode/laptop-mode.conf).
This also affects suspend/resume/hibernate/thaw modes, due to symlink from /usr/lib/pm-utils/sleep.d/95hdparm-apm
This effectively prevents hdparm from managing HDD's APM.

2. /usr/lib/pm-utils/sleep.d/01laptop-mode , when it finds /usr/sbin/laptop_mode, runs it with the arguments "auto force". This results in error: laptop-mode-tools is disabled in config file. Exiting
