Based on the other solutions you may have a few options that are close.

You might get by if you are willing to write your own custom notification 
script. Nagios should notify every N minutes to the script as long as a 
warning or critical level exists.

The scripts should keep progress of the performance data and only send out 
a real message if the performance data merits it.

No modification of the check script is needed but a custom notifications 
script.

Or if you write a custom check_disk to get rid of some of the details you 
can use stalking. But with the current level of details it would fire up 
every round. For exmple "DISK OK - free space: /boot 66 MB (70% inode=99%)"

The percentages are fine but the more exact counter will be a problem if 
you enable stalking.

Or you write a wrapper script to loose some of the output so stalking 
seems to make sense. Propably the easiest way to do it and the most native 
Nagios solution.
