Edit php.ini (For newer Redhats, that's /etc/php.ini)
Find the "file_uploads" line.
Change it to:
file_uploads = On
Restart apache.
Relax and enjoy!

(That speed limit thing strikes me as more PITA than anything else, but anyway...)
Good point, and it serves to highlight that you should always be up to speed on security issues for any 'net connected software you are running. If not that, then at least be sure you are always running the latest, greatest versions.
Really, if you aren't keeping up with security alerts and/or running the newest versions, a vulnerable PHP may well be the least of your problems. Other network-oriented software like ssh, ssl, sendmail and login have all had serious security issues recently -- many with known exploits. (I had one of my own boxen r00ted last November via a vulnerable version of sshd.)
For the really paranoid, you should not only be checking the security sites daily, but also run Nessus, or something like it to scan your boxen on a regular basis.
