set-defaults [hit Enter] boot hd:,SystemLibraryCoreServicesBootX [hit Enter]Hopefully your Mac will boot to OS X or (if the trick doesn't work) to a white screen with an error signal instead of the Apple logo. Don't panic, just switch off the box and try the commands again (it actually took three tries for mine to come back). Remember to re-set your startup disk to the Mac OS X folder in the Preferences -> Startup Disk after you get running again!
If this trick doesn't make your Mac come back, you may want to go and read this document, and additionally this info on Open Firmware by Apple. Finally, this one is a quick info page for OpenFirmware, very clear and useful.
Good luck.
