It looks like this is a known problem with your hardware. See here:

Yes, that's a 'buntu site, but the problem refers to the kernel, which is pretty much the same across distros.
Don't worry if you do not understand
all that's written there, because you'll get the idea
I have the same problem with my Sony VPCF11CSE, but I hate touchpads anyway, so disabled it and use a USB mouse instead.
In time, the kernel will, eventually, catch up with this new hardware, and recognise it properly. Unless someone has better advice, I recommend you be patient. At least it is working, if not "configurable".
