Most tyan boards come in single and dual variants. The only difference
between the two is the missing socket and one chip (at least for the
Tomcat). The rest of the board is identical including the BIOS. It is
the BIOS that is telling linux that there is a 2nd cpu even if there
physically isn't one there.

This has been discussed before. Linus won't put it back into the config
menu until the dependency system is made more intelligent, so that if
one config option changes, 90% of the kernel doesn't get recompiled
anyways.

The APIC is the controller used to synchronize multiple cpu's. It is
only present in Intel cpu's, which is why AMD and Cyrix processors
cannot do SMP (they use OpenPIC, which is an open standard).
