The idea to provide some template for (PCI) driver development is
definitely a good one. Your approach already look quite nice, but it is
generally wise to apply such templates at least on two different drivers
to see what may be missing, what needs refinement, or what is not required.

A few comments already: it would be nice to add kernel 2.4 support to
your Makefile. Keep an eye on potential "over-design", i.e. avoid
wrapping trivial things, rather concentrate on providing templates the
user can fill in stuff directly.
