Login problem after fresh install -> session cookie not sent

Yesterday I downloaded and installed drupal 5.1 on my test server, but after I've created admin account, I couldn't log in. I typed username and password, but after submit, i've been redirected to homepage.
Then, I searched over and over the tons of topics related to "Login problem" and I tried *everything*, I thought... None of them solved my problem, so I took my PHP knowledge and started to discover the problem... After a while (half a day...:/) I've figured out that the problem is with session cookies. Drupal should send a session cookie whenever a user (authenticated or not) opens a page, but in my case, drupal did nothing.
Then I tried the session_start() function in a seperate file with those ini_set()-s in settings.php, but it did NOT send a cookie at all. Then I tried on a different server and it has worked. So, it is a server problem, ok. I tried different settings in php.ini, httpd.conf, etc...
And then... I found the source of the problem: in my php.ini, there is a line: session.use_cookies 0. Hmmm... OK. But in settings.php there isn't any ini_set('session.use_cookies', 1); so the session_start function doesn't send any cookie.
After I've added this line to settings.php, everything works fine: ini_set('session.use_cookies', 1);

So please somebody make a patch or simply just put this line to the CVS, so it could be available for everyone as soon as possible! Thx.
