I have an additional problem on my dual-boot U12.04/Win7 machine.  I
need to have both on this machine.  I need to have access to software
that will not run on and has no equivalent on Linux.

If I boot Ubuntu and then Windows, the lid-close suspend does not then
work on Windows either!  The only cure is to shut down, and then stick a
pin in the tiny hole in the bottom of the machine that causes some sort
of extra-hard shutdown.  This suggests to me that somehow, the Linux
kernel (or some other bit of GNU/Linux/Ubuntu software) seems to be
breaking the lid switch.

As an aside, if you do this hard shutdown, it is not possible to get the
machine going again unless it is connected to mains power.  If it is on
battery, the on-switch has no effect.  This has nothing to do with
Ubuntu/Linux - this seems to be a design "feature" of the machine.
