2 or 4 only, 3 is for such esoteric machines as SPARC. Worse, 4 is ONLY
Xeon or Pentium Pro. Quads are extremely expensive (i.e. motherboards
cost more than your mother).

In theory, you _could_ install only three processors into a quad board.
I've never heard of this being done.

 As of now, I am not familiar with the Israeli market of such workhorses.
 I would like to know if and where are the following:
 1. Vendors

AMI has such boards. Dell, Compaq and IBM have such machines (as said,
4 CPU). Two CPU boards are dime-a-dozen.

 3. Users who have the time, knowledge and inclination to give advice to a
 newcomer.

Ask away.

 For a project I may need a SMP motherboard with the following specs:
 1. 3 processors.
 2. Linux support is mandatory.
 3. Processors from Intel or its competitors - advantage (i.e. Alpha,
Sparc, etc. are at disadvantage).

I never worked with SMP but I do believe that the following LDP docs can get 
you started:

4.1.7. Parallel Processing

   Parallel-Processing-HOWTO, Linux Parallel Processing HOWTO

   Updated: January 1998. Discusses the four basic approaches to parallel
   processing that are available to Linux users: SMP Linux systems,
   clusters of networked Linux systems, parallel execution using
   multimedia instructions (i.e., MMX), and attached (parallel) processors
   hosted by a Linux system. 

   SMP-HOWTO, Linux SMP HOWTO

   Updated: October 2000. Reviews main issues related to SMP
   configuration under Linux. 


Just to emphasize: although 
1. I have no SMP experience
2. I never read those docs
3. it does not seem directly related to what you were asking about,
if I were you I would consider starting with those.

I hope it helpful.

   You are right that there are no Israel-specific issues with non-Redmond
   (or, rather, Santa Clara) hardware. However, a foot-and-mouth count of
   people who have such beasts at home would be nice, as well as possible
   pooling of semi-defunct hardware into something that may be used.
  
 
 
  uh. it would be nice indeed (speaking as proud owner of (totally)
  nonfunctional sun-1 (sic!)). this is somewhat orthogonal to linux
  though, so I doubt this list would be a good place for it.
