Just adding ide-generic to /etc/modules (a Debian-specific file that lists 
modules to be unconditionally loaded on each boot) is much easier.

In fact, if a module has been loaded by one rc script, agents should catch the 
resulting hotplug events. So the order _should_ not matter with good agents, 
except for the number of duplicate fake hotplug events. The problem is that 
there is no "ide.agent" file. Sorry for my initial not-very-correct 
description of this ordering problem.
