Well, I've never heard any Linux distro claim that they support all laptops, but you should be able to make it work. You just have to write down all of the hardware that your machine has. You should be able to configure X, the sound, CD/DVD burning, and USB. I don't know about FireWire, since I don't have it in any of my equipment.
You linux install *should* be straightforward, but be prepared for the possiblility of making a custom kernel. Also, the biggest snag for you (as it has been for me) could be configuring X to work with your LCD screen.
