I don't know the correct answer to this question, but i thought of a
possible work-around in the event the answer is "no".
Could you write a CGI program that serves the file? I don't know where
Apache's 4 GB limit is. But if the limitation is in how Apache accesses
the filesystem and not in how it manages network connections, then
maybe a program that is capable of reading large files could get around
the limit. This would most likely require mangling the URLs to the
large files to really point to the program, unless you can do some
mod_rewrite magic.
