You may have a shot at getting this memory to run but I wouldn't bet the bank on it. If you can ever get into the BIOS (I know you haven't been able to get any kind of post yet) you can try resetting this memory to auto or have a go at manually setting your timings. This is probably going to be a stretch and more than likely, you're stuck with a square peg and a round hole.
As to your Crucial page - my bet is this isn't the module you bought. Is your stick 128x64 or do you have a higher density module from a different manufacturer?
Here's a bit more re: spec summary.
