After further testing, it appears that IPAPPEND doesn't work when used in
conjunction with linux.c32 which is used to get around the memory hole on
older systems :)  So if it isn't in the append line, then it isn't passed to
the kernel cmdline.  Using menu.c32 this isn't a problem however, and
IPAPPEND is appropriately added to the boot parameters.

To break it down...

No menu.c32 - linux.c32 doesn't work with IPAPPEND, but bare kernel and
images work fine
with menu.c32 - linux.c32 and bare kernel work with IPAPPEND

If I had to guess, I would say that the linux.c32 doesn't do any additional
parsing and overrides any pre-existing parsing that was done with the CLI.
Thus doesn't know about the additional "features".  So this could be marked
as a bug or missing feature, but at any rate, sorry for the trouble :)
