one would really think that such a counter exists...

if the readout time is not an issue, he could read only the counter
overflow and increment the counter from the controller until it overflows
after he stops counting the input (multiplexed counter clock input). that's
almost serial :)

or a combination: use some reasonable count number to divide the input
(10..12 bit), which must be enough to allow you to count the overflows
reliably. after the gate time, you clock the counters up to the next
overflow, much as you handle the pic's prescalers when timing with them.
