Not sure if WHM does it...... it does a LOT of shite but I'm not sure of that. If WHManager could give you the current loaded modules in apache that would suffice in providing you the details you are seeking........
**feature request hint**
:p For now, it's easy to tell by the apache main error_log,
cat /usr/local/apache/logs/error_log | grep PHP
That will print out the line that shows loaded modules and apache's current version. FrontPage 4.0 = 2000 server extensions, FrontPage 5.0 = 2002 server extensions.
g00d luck.
