Package: xsysinfo
Version: 1.7-6
xsysinfo only uses the first four items of the cpu* lines in /proc/stat.
hence, it tries to make us believing that we need a new cpu when executing
i/o-intensive tasks as `dd if=/dev/sda of=/dev/null bs=8M`.
This is a consequence of an inappropriate normalization.
the patch attached fixes this problem for sarge and etch, but, it might
be that kernels 2.6.21 and above need further code (see also bug #413807).
`uname -a` yields
