1) Maybe dead PRAM battery?

2) Booting into Open Firmware and reseting the NVRAM might help:

Hold Cmd-Opt-O-F at boot. At the command prompt, type the commands (each followed by a <Return>:

set-defaults
reset-all

the responses to these commands should be “ok” and then an reboot automatically.

3) I think that sometimes cursor artifacts are related to video card issues, so you might try reseating the video card in its slot and reseating the cables.
