On Fedora and downstream, the file you probably want is /boot/config-<name of your kernel>. Also CONFIG_SMP is Y by default - at least on AMD64 (x86_64) platforms. For example, I am using 2.6.40 on a F15 X32 development system, so the name of the configuration file is config.2.6.40.4-5.fc15.x32. (x32 is not a typo, it is a new emerging psABI)
If the OP installs and runs cpuid, we will have a much better idea of what the actual cpus think they are. I suspect that cpuid will return the expected values but I think we should eliminate this possibility or that some cores have been disabled by the BIOS. BTW, There was an interesting discussion on FreeBSD back in 2010 re E5530s and missing cores. Search for "FreeBSD, E5530 cpuid acpidump." Turns out that the missing cores were disabled by a BIOS setting.
I've got a E6500 with 6 cpu's over 3 cpu boards.
we lost one cpu should the box keel over ??
I wouldn't have seen this as a Single Point Of Failure
