I am guessing that "keeppxe" is needed.

Although versions "2009" and "2014" are not really "versions", "2014" is 
probably version 6.03, which is still/yet not supporting "keeppxe". This is a 
known problem.

BTW, for menu.c32 "2014" you should also need its corresponding libutil.c32 
(although, if your "default" file only has one entry, then menu.c32 is useless; 
i.e. the menu won't show up anyway).

You could try the binaries from Debian's "experimental" repo (replace _all_ of 
them, not just pxelinux.0). Feedback is appreciated.
