I've got a setup like this running on Windows and it was very difficult 
even then, shared libraries etc. throw a spanner in the works.

You could always run php5 as a cgi and associate it with .php5 scripts 
(and use some mod_rewrite jiggery pockery to rename all .php to .php5 
when you want to test it).

Somthing like:

RewriteEngine on
RewriteBase /
RewriteRule ^([^.]*).php(.*)$   /$1.php5$2

not sure if that's 100% correct (regexp people out there, is it?) but it 
could serve as a good starting point.

A jail may be the best option available.
