I leave the message below for the record of my bad day and in case it helps someone else.
T'was the 'i386 uni' that confused me.
A look at
http://www.centos.org/docs/5/html/5.2/Installation_Guide/s2-x86-bootloader-smp.htmlconfused me further.
A quick
[root@mmm ~]# cat /proc/cpuinfo
processor : 0
vendor_id : AuthenticAMD
cpu family : 15
model : 67
model name : Dual-Core AMD Opteron(tm) Processor 1210
...revealed the answer - only one core in use.
This was useful:
http://www.redhat.com/magazine/022aug06/departments/tips_tricks/(scroll down to 'How do I detect a dual-core CPU')
I edited menu.lst which was defaulting to up kernel and now OK.
I searched for a bug and found something similar #4802 but dead.

Hi all
see subject: I have just installed clean SME 7.4 on this box and on boot it reports it only is loading a single processor kernel (no smp option offered).
I have checked on CentOS and can only find reference to AMD dual core support in the 64-bit kernels.
Does anyone know if this CPU is fully supported in 32-bit SME 7.4?
TIA
