It can do either the entire server, or for specific handler types:
http://svn.force-elite.com/svn/mod_load_average/trunk/src/mod_load_average.c

This way you could disable CGI when your LA is above 10, and then 
disable everything when your LA is above 100:

     LoadAvgMaxByHandler cgi-script 10
     LoadAvgMax 100
