swap plugin - swap in/out does not work for kernels <2.6

swap plugin - swap in/out does not work for kernels <2.6

It works on RedHat9 and 6 (don't ask). A more gracefull solution is
having a configuration option for choosing /proc/<foo> format I
suppose...
Hope it helps some sysadmins like me that are forced to maintained
anqituities in production.

Cheers
