Hi Chad,

It might be a bit useful to know what it is you're trying to do.  The
GSoC code from last year is obviously not in its final form (it's meant
to be integrated into the Syslinux core, which might happen as early as
as later this year if all the stars align.)  Are you simply trying to
test it out and experiment, or are you looking for a specific application?

In the earlier case, it would of course be good if we could straighten
things out; in the latter case we may want to verify that your
application is compatible with the intended future setup.

As far as "append" is concerned, at least in stock Syslinux code there
is only support for a single "append"; a later one will override the
first one.
