For an example, see here: http://nanchatte.wordpress.com/2008/04/27/128gb-large-hdd-lba48-support-on-the-g4-cube-with-leopard/ IIRC, there is a command in OS X that can be used to modify Open Firmware once the OS is booted. I think the command is "nvram", but I'm at work right now and don't have a PPC Mac handy for testing. Actually, I got the command right. Here's the man page for the nvram command.
