Sergey:

I will just do following for now, so maybe overwriting fastcgi_params might not be such a bad thing on freebsd since we will always get
a new copy of anything that changes automatically, i've just thrown the geoip values in another include as follows:

location ~ \.php$ {
#fastcgi_pass 127.0.0.1:9000;
fastcgi_pass unix:/tmp/cgi2.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
include fastcgi_params_geoip;
}
location ~ \.pl$ {
fastcgi_pass unix:/tmp/cgi.sock;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
include fastcgi_params_geoip;
}
