I thought it was OF based, but what do I know.
Are you asking on a real machine or on qemu? On real PReP hardwrae you can find both OF and other firmware like PPCBUG...in both cases they dump residual data. On qemu, jmayer wrote the openhackware bios with is supposed to be some minimal OF-like thing...it dumps residual data too. -Matt
