I spend most of the day at it, but, not being very good at wound up giving up.

I did figure out how to get the kernel tree for my running kernel and
rebuild that one module
against the running kernel instead of as a new kernel and installed it
into the running kernel
replacing the existing module. I then hard coded the vertical and
horizontal offsets to make
things center up. Everything works but I ran out of time trying to get
the full crop patch to apply to the
current version of the module. The patches for my change are simple,
just changing a few constants.
I think it would be difficult to try to track the status of the module
and continuously update the full patch
to add the crop controls. I've got a simple script that I run when I
update the kernel from the fedora
repository that patches a few things and compiles a few modules
against that kernel and replaces
the standard modules. It only takes a few minutes. If I take the
system down for more than that,
I get yelled at.

Hopefully the changes will make it into the module, and then into the kernel.

Do you know what process is used to reduce the size of the modules?
When I compile a module it
is several hundred kilobytes. The same modules that come with Fedora
are a few tens of kilobytes.
Do they use strip to get rid of debug info? I could not find
documentation about that anywhere?
I don't even know if it is a fedora thing or a generic thing.
