Linux 2.2, that's extremly old - ages from before I took over it's
maintainership.  But the code actually looks okay.  Sure you don't want
to upgrade to a piece of software from this decade?

For custom kernels that will save a tiny amount of memory and give a small,
almost unmeassurable performance gain.  You lose the advantage of for
example being able to re-initialize a subsystem by unloading and reloading
it's module.

Given all that what learned about problems with the 2.2 module loader we
can probably declare it a buggy horror trip from today's perspective.

The 2.2 6pack driver looks ok, certainly up to the standards of those days
and I wouldn't expect any problems with it from linking it.
