I haven't done this with Linux, only Soekris+OpenBSD, but the principles are the same. PXE, kickstart, monitoring via serial port. Change console settings to point to the serial port as per Giles. Use a USB-to-serial converter to connect to a laptop running a terminal program, or serial cable with a dekstop that still has a serial port. May need a null-modem cable, I don't remember.
