What you wrote is similar to what I would expect to work, which would
be this:
class special inherits base {
Class['apache'] { mpm => 'prefork' }
}
node 'specialhost' {
include 'special'
}
That's the standard syntax for subclasses overriding their parent
class's resource's parameters. In practice, I'd put the subclass
definition in its own file in a suitable module, of course.
