I want to say that nothing worked, in changing configurations, but 
moving the system to the first KVM did.

While in init 3 boot mode, I ran:  Xorg -configure

It did not recognize the mouse.

I did not read further in to see that I should 
have tried xorgconfig and see what it would do.

Well, since the mouse is working now, I think I am going to try these 
two to see what they do...

Again, thanks for all the great help.  I really don't know how I am 
going to document this one.  Probably has something to do with the 
power in my KVMs.

BTW, they are old ATEN Master View plus CS-138D.  These are 2U 8 port 
KVMs that support cascading from ports 1-6 (cannot cascade from 7 or 
8, and now I think it is a power problem).   According to ATEN's old 
records, these were suppose to be for the EU market.  But they were 
in original manufacturing packaging with 110 power transformers.  I 
currently have 12 ports in use.  One goes to my work bench where I 
have an old KVM that does not support the cascade, so I have to 
switch that manually (allowing for multiple systems in 
development).  If I could find a CHEAP 1U 16 porter that could use my 
current cables (well that may take a 2U), I would jump at it.  I will 
probably have to, as in another location I had a CS-104 and put in an 
LCD monitor, but the 104 could not drive it.  I suspect that when I 
go to replace my very old CRT here, I will need that new KVM!  Oh, 
for systems in production in my NOC, the score card is:

NT              1
W2K             4
XP              1
Centos  4
Astaro          1

One of the Centos is suppose to sundown the NT.  But I have to spend 
the time to get SAMBA with PDC support working on that one.
