I haven't followed this thread too closely but it sounds like the negate
plugin might be useful. negate changes OK to CRITICAL and vice-versa.
You'll need two separate tests though. For example say normal was
between 4 and 7, critical above 7 or below 4.

check_mrtg -c 8 # CRITICAL if 8 or above, everything else is OK
negate check_mrtg -c 3 # CRITICAL if 3 or below everything else is OK
