Excellent - so you have a functioning hibernate and suspend with an 
encrypted /var /tmp /home /swap configuration?  Although you had to do 
this from install using the alternate install disk?  It seems migration 
is not advisable.

Guess it's about time I cleaned out my main system anyway if that's what 
I need to do to enable filesystem level encryption.

What system are you using and any overhead noticeable?  Apparently even 
an Atom CPU (netbook) can work quite happily with filesystem level 
encryption with plenty of RAM (this netbook has 2GB) for caching.
