Adding more CPUs will not affect the load average if it's IO related.  If it's 
CPU usage related then more CPU power should decrease the load average.

Of course kernel bugs could be triggered by a different hardware 
configuration, but that's not a likely possibility at this time.

I suggest checking for any cron jobs etc that might have caused high load.
