I am working on a Dell box with Knoppix 3.3 9/03 installed on the harddisk. 'cat /proc/cpuinfo' shows a single Intel P4 2.40 GHz. The same is true for the remastered CDs.
When I boot up (on the same box) the recent LocalAreaSecurity.com Knoppix based live CD, I get two Tuxs, and it finds 2 P4 2.40 GHZ processors.

Why? Is it in the SysLinux version? Any way to get to that other cpu?

This remastering can use all the cycles possible. Having the second processor might cut down in the making of the compressed ISO.
