So I need to do this for local mounts, or for all mounts?  I have /, home, two 
windows partitions and some nfs mounts.

The reason I want to try it is that the laptop appears to be running much 
hotter under KDE4 than it did under KDE3, so I want to test whether 
over-frequent updates is the reason or not.  For instance, if I minimise this 
message then maximise it again, the fan will start.  Obviously, if there was 
a problem with the temp mounting I would take it out again.
