I made a try with 1.5 cvsupped a few hours ago. It seems OK so far. The 
reason to upgrade was that I intend to use nullfs functionality for some 
jail configs. Sorry to say, I'm not going to be able to test this issue 
within a few months, becuse I have only one 4way box at the moment.

Best regards,
