But the kernel, using C code, uses those ids to match drivers to
devices. So we have to create C structures out of those ids some how.

The idea was that since the kernel already keeps track of these ids, we
might as well export them to userspace, so that it too can see what the
kernel support. That brought forth the modules.*map files and enabled
the hotplug scripts to automatically load a module based on a device id
(this is much nicer than other os schemes which force a text file to be
created for every driver listing these ids. They are usually created by
hand, and can get out of sync.)

I agree that now that more and more tools are using this data, we should
put it into a form that everyone can easily get at, without having to
parse module attributes or even the modules.*map files.

Any suggestions that do not involve XML? :)
