Laca,

Changed this to a bug fix for 
???http://bugzilla.gnome.org/show_bug.cgi?id=534335
Calculation CPU load depend on two files kstat.h and sysinfo.h,
especially sysinfo.h is different between Solaris and Linux. So I'm
incline to use "#if defined(sun) && defined(__SVR4)"

Actually we have pushed dozens of patches upstream. The remaining
patches are partially Solaris-specific policy decision from PM team,
partially not acceptable for gnome-2.22 branch but already in SVN trunk.
Anyway, I'll try to push upstream as much as possible.

Thanks,
-Simon
