My problems aren't those who update through the backend but those who 
update manually (downloading from wp.org, unzipping, uploading to blog).

I think I'm going to check for the PHP version and print a big hint in 
the backend (maybe even in the dashboard), and add a  small hint in the 
blog and only execute PHP4 code, so that the blog will not stop from 
rendering completely.

BTW: I stopped the auto-update by using 
add_filter('option_update_plugins', 'plugin_prevent_upgrade');. Works 
for me, I will blog this solution soon (or you can look it up in the 
"pagebar" plugin.
