Ben, Yes you're right, we are using mod_php, but only because no other alternative was required up to this point.
This server hosts many vhosts, and I've read that SuEXEC isn't appropriate for multi-site installations of apache. I'm looking into SuPHP right now, but their site _seems_ to be down. Thanks again...
