So my soon to be brother-in-law asked me whether I had checked that my new MacBook did not have the same fault as my PowerBook - I was so busy installing updates that I hadn't checked that out, so as soon as the machine was done doing what it was doing I tried to but it to sleep and wake it up - and it w0rked!
WOHOO!
So now I have a long TODO list ahead of me of moving all my stuff from the PowerBook to the MacBook so I can get the PowerBook handed in for repairs.
