If your child nodes are not manageable servers (like ordinary PCs),
you are pretty much out of luck: you can't even power cycle them
remotely without hardware hacking.
Your next best bet is a serial concentrator. Put multi-port serial
cards into the head nodes, and wire up the childs. Yes, this is
double cabling.
Two-way network access to pxelinux would be somewhat complicated to
add, but an output only network console, like netconsole in Linux,
wouldn't be particularly hard. Having a watchdog in the clients and
access to the tftp server could get you a long way with this.

You can achieve the same by changing the default menu item on the TFTP
server before rebooting the client.
