Hi, pm-utils maintainer here.  What version of pm-utils are you using?

If you need to unload modules across a suspend/resume or hibernate/thaw, 
you can have pm-utils unload them using the SUSPEND_MODULES parameter -- 
just drop a file in /etc/pm/config.d with the line 
SUSPEND_MODULES="problematic modules", and pm-utils will unload and 
reload them across suspend/hibernate.  Which modules are you having to 
unload to make things work?

Also, what is the HIBERNATE_MODE environment variable?

Hmmm... among other things, pm-utils is intended to be an abstraction 
layer that higher-level code can call without having to worry about 
whatever bizzare workarounds any given machine requires to sleep and 
wake back up.
