On an RH7.2 box, running the latest RH released versions of PHP (4.1.2), PHP-MySQL (4.1.2) and MySQL (3.23.58) I have installed MediaWiki 1.4.7, which initially appears to be working fine. However, all attempts to edit pages, anonymously or logged in either as an ordinary user or WikiSysop, produce the same result. Pressing 'Save page' has the same effect as pressing 'Show Preview'. The Preview doesn't contain either the old or the new page, but once again offers the option of either a Preview or a Save.
The symptoms sound a little like those in this thread: http://mail.wikipedia.org/pipermail/mediawiki-l/2005-April/004840.html
I tried adding the session_save_path(...) statement to the end of LocalSettings.php, but saw no change in behaviour.
If messing around with the session settings doesn't do it, you should consider upgrading to a more modern version of PHP. (There are a lot of bug fixes in later versions of PHP as well.) Or better yet, a more modern version of Red Hat (7.2 is long since past EOL and not receiving security upgrades, as I recall).
