I understand that the English proficiency requirement came into effect on March 5th 2008, although compliance is patchy.
There's a list of test centres on the DCA web site -

Once you have the exam result, then you'll need a DCA form 48-EP and RM 20 to have the proficiency endorsement added to your licence (presumably via another trip to Putrajaya).
Another gotcha is that a PPL renewal needs a letter from the applicant's employer including expected length of employment. Didn't see that one coming...
