[syslinux] isolinux boooting update

[mike at tiedyenetworks.com]

An update to the problem I reported earlier -

	 A kind list reader, Michael K Ter Louw, suggested I try syslinux
v1.67, and viola!, my problem went away completely. So something between
1.67 and 1.71 got broke with respect to isolinux. Hmm...

	Another kind list reader, Seth Kurtzberg, was kind enough to make
and effort to send an updated initrd; although it didn't solve the
problem, it was quite a generous gesture, thank you.
