No "Using locked pages for buffer pool" in SQL Server log
As I see, you're using a 32 bit system, so please follow the information from this MSDN article: Do I have to assign the Lock Pages in Memory privilege for Local System?. It's from MS's own CSS team.

Quote from it:
"If you are using 32bit systems, the messages and algorithm are slightly different. The message you should look for in the ERRORLOG is the following: 

Address Windowing Extensions is enabled

If the privilege was not set correctly, you will see this message:

Could not use Address Windowing Extensions because the 'lock pages in memory' privilege was not granted.

These messages will NOT show up for 32bit systems unless the configuration value 'awe enabled' is set to 1. The second message can show up if the "Lock Pages in Memory" privilge was changed after successfully configuring AWE and then the privilige was cleared OR you used RECONFIGURE WITH OVERRIDE and the privilige was not set. "

Another detailed article regarding "Lock pages in memory" is from well known sql writer Glenn Berry: SQL Server and the “Lock pages in memory” Right in Windows Server.
