nginx 1.0.5. У меня работает вот с таким конфигом:

location / {
root /path/maxsite;
index index.php index.html index.htm;
try_files $uri $uri/ /index.php?q=$uri&$args;
}
location ~ /\.ht {
deny all;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/local/www/nginx-dist;
}
location ~* \.php$ {
fastcgi_pass unix:/tmp/php-fpm.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /path/maxsite$fastcgi_script_name;
include fastcgi_params;

}
