Another Capital Gains Tax Question!!

Bought a house in 2004, lived in it until April 2008. Rented it out then until Nov 2009. Just sold it for substantial loss. So no capital gain but significant loss I want to carry forward. Will revenue credit me with the full loss or pro rata it for the time I lived versus the time it became a rental property. Have searched the revenue site and cant find an answer to this.

Thanks Folks

PPR period is exempt and any loss arising on that period not allowable.
The total loss will be apportioned.
