Be aware that some distros have hacked their meminfo (proc and 
/sys/devices/system/node/node*/meminfo) output to be more compatible with 
recent 2.6 kernels but not updated to the new ZVC counter scheme. On those 
kernels (<2.6.17) counters may show weird values and the sum of the per 
node counters in sysfs may not yield the same amount shown in 
/proc/meminfo.
