Does
this link contain the specs for your laptop?
If so you're trying to put OS X on a laptop which uses a single core Celeron. I'm not saying it can't be done, but if it is done I would think it's less common. Not sure what your alternatives are.
Out of curiosity, which flavor of OS X did you want to try to install? Leopard or Snow Leopard?
