Comment 20 for bug 761809

As a first step it would help to have a bit more help in reasoning why those modules are needed. The virtual package was targeted to be used as a guest kernel in a vm. To keep the package footprint small some modules were not packaged. Now to get them added to the older releases it helps to have a real-world use case to make the argument.

Lucid (10.04) is even more a special case. Back then, the virtual packages are just module subsets of the generic-pae (i386) or server (amd64) packages. While later virtual became its own flavour which allowed us to use slightly tuned compile options.
So, as confusing as all of this is, in Lucid one can use generic-pae or server and get all modules, while later on there is a difference (though mainly whether xen drivers are built-in or modules).
