It might be memory related. I'd remove the battery and RAM, and test the memory slots one at a time with a single module of known-good RAM, probably also resetting PMU and PRAM each time you power up with a different RAM config. Reset the PRAM three times past the initial power-up chime -- this does a more comprehensive reset than a single PRAM reset.
It's unlikely, but before giving up on this machine I'd probably take the hard drive out, format it on another computer, and try again, or even install the full OS to the hard drive on another machine, and then see if you can boot from the laptop to that hard drive in target mode, or with the HD put back in the machine.
-I always keep hard drives around with the full OS installed, because it's always interesting to put them in "bad" machines and see if it makes a difference. Sometimes a machine cannot deal with the installation of an OS, but if you give it a HD that already has the OS, for some reason it can decide that's tolerable and start working.
