    So presumably this needs to be fixed in 2.6.32.y and other longterm
    series as well. Though there seems to be a whole series of fixes
    required in 2.6.32.y!

    Are you going to look after that, or should someone else prepare
    backports? (I'm certainly not volunteering - I don't have the VM
    knowledge to work out what needs doing.)
