Hi Martin,
I'm double checking right now, but it might be a day or two.  The 
machine in question is in germany, and is in production right now, so I 
have to contact the system administrator to get the information.

I do know that for i386, I saw all 16 CPU's and had no problems at all 
(with SL 4.4).
For x86_64 my data somehow got blanked.  You know you mean to save a 
file and push the wrong keys, and you don't notice until your test 
system is away in production.

I will get that information and update the page if it needs be.

Thanks
Troy
