Log messages at 'notice' level are always output regardless of
LogLevel, unless they are using syslog for logging in which case
whether it comes out is dictated by syslog settings.

If you have no control over Apache installation or Python installation
then you probably have no way of getting around it. Sounds like your
web host is being a pain when it wouldn't be too hard for them simply
to update binary RPM for expat package to 1.95.8. There is no need for
them to recompile anything, just installing the updated expat is
enough.

If the web host is advertising Python web hosting services then they
are being misleading when things like this aren't going to work.
