The standard kernel won't use two processors, but you might want to try
contacting Alan Cox to see if he wants alpha-testers.  He tells me he
runs doom etc on Linux/i386-smp, and I do have a slightly old patch-set
to do that.. 

SMP support will probably be part of the standard kernel in the
not-too-distant future (like a few weeks).  It's currently using the
simple "one large lock" approach, so it's not optimal, but it's probably
good enough for dual-cpu setups.  And as usual, first versions may not
be very stable. 

(SMP will be a compile-time config option, so that people without SMP
machines won't take the performance hit from it on UP machines, in case
people are worried.)

		       SCO Files Lawsuit Against IBM

March 7, 2003 - The SCO Group filed legal action against IBM in the State 
Court of Utah for trade secrets misappropriation, tortious interference, 
unfair competition and breach of contract. The complaint alleges that IBM 
made concentrated efforts to improperly destroy the economic value of 
UNIX, particularly UNIX on Intel, to benefit IBM's Linux services 
business. See SCO v IBM.
