DDL seems to do a decent job of abstracting things, e.g.:

OMF loader: http://dsource.org/projects/ddl/browser/trunk/ddl/omf
COFF loader: http://dsource.org/projects/ddl/browser/trunk/ddl/coff
And the root dir: http://dsource.org/projects/ddl/browser/trunk/ddl

Anyway I'm not suggesting it's a complete implementation, but it might
be worth taking a look. It's BSD licensed, hopefully that means it's
ok to look at and maybe extract some useful code or ideas from it.
