You might not be interested in the absolute values of these
counters but more in the differences (i.e. growing rates) between
two invocations of the stat program. This seems to be just like
the collisions and errors counter values in the ifconfig output.

I guess there's no need to fix something, it's not broken. I
feel you don't care about the number of irqs in the past six
months (I couldn't think of an application's use for these
numbers). I think you want to know how much moves your system
makes upon certain actions lasting for some minutes or hours
(when causing heavy load of work or something). And this is what
the counters are able to cope with.
