Don't think it can be a hardware issue. First time I did the install on my laptop, I got the four options. Second time I did it, same machine , I got only two options.
With regard to the swap partition, perhaps it's worth pointing out that it's a good idea to fix the size you want before hard disc installing from the cdrom. Knoppix will use any swap partition it finds and while it is being used the size can't be altered.
