Something you certainly tried, but I ask the question: did you try to
automatically unload/reload module when going to suspend mode?
I remember there is such framework around suspend/hibernate framework:
simply list modules somewhere and they are automagically unloaded when
goind to suspend mode and restored when resuming.
