config.php ordering problem

Hi, I've been working with back-end for awhile. I've run into a config.php 
problem and Mike Gifford suggested I follow it up here.

The symptom is that when $_PSL['timezone']['engine'] is true, any errors 
logging in via login.php cause a blank page to be returned.

The problem is this:

BE extends functions.inc getHeader() to add current date to the template. This 
uses psl_dateLong(), which uses psl_strftime(), which needs the tz library 
and classes if $_PSL['timezone']['engine'] is set.

Trouble is, config.php calls page_open() _before_ the AddClassRequirement() 
and AddLibraryRequirement() calls for tz and friends. In the case of a posted 
bad username or password, page_open() tries to render the login form which 
causes getHeader() to be called, and the tz library call blows up.

So my question is - why are some of the Add*Requirement() calls (particularly 
the ones for tz et al) in config.php after the page_open? I see in  
phpslash-dev CVS config-dist.php that this is still true. What would be the 
implications of moving these Add*Requirement() calls to before page_open()?
