We received our SUN X4600 with 8 dual opteron processors and 64GB RAM 
and I turned it on yesterday. I had no problems installing Scientific 
Linux 4.3 but I had a little difficulty with openafs because the 
kernel-module-openafs was not built for the ELlargesmp kernel  on the 
4.3 iso images. This kernel was the default installation kernel. However 
I found the required RPMS on Scientific.Linux..../40rolling  and 
downloaded them and they seem to do the job. So now all I have to do is 
install the applications that will be used and put some users on the 
machine.
(Sorry Jon Peatfield - it looks like it might work for us so you are out 
of luck for now)
