Probably using the default HZ of 1000 in which case the 10000 differential 
would seem sane according to your numbers (HZ 100 yields 1000 differential).  
The rate in 'vmstat -i' is misleading because it is the total interrupts 
divided by the uptime of the box.  Recall that part of the boot is spent with 
interrupts disabled.  systat -vmstat gives a much more usable interrupt rate.
