This patch is just a (shameless) copy from bug #28 [1]. The original patch has been sitting there for a couple of years now, and it was based on Syslinux v 4.05. The patch I am posting here is just a re-base on v.6.03. Whichever inadequate formatting (tabs, trailing spaces...), or any kind of correction that was required for the original patch to be accepted, is probably still required now.
