In certain situations with older monitors. Make sure the bootup is not trying to change into SVGA mode at boot. A lot of distros try to change into SVGA mode asap. Something like "no-framebuffer" at boot should fix it.

The situation is as follows:
The monitor displays POST, then LILO, then booting, but somewhere in the init process the monitor shuts off and remains off until it wakes up on shutdown -r now, at which point one can switch between virtual consoles and see the messages that root has echoed to for instance /dev/tty4.
Any ideas? It's not a wiring problem.
