What I asked was, doesn't SuSE's installation scripts detect the proper CPU's and load the kernel compiled for the correct Processor family?

No, it loads a default kernel that will work for all Intel x86 processors since Pentium I.

If you want to run a kernel that's specifically built for your hardware, you'll need to configure and build it yourself.

Also I just now checked another P4 Xeon box that I have and in that it has properly loaded the P4 Xeon processor family kernel. Anyone with an idea here?

Where did you get the P4 Xeon processor family kernel? SUSE 9.3 does not ship with a kernel built for P4s, AFAIK.

Thanks all of you. I was wrong looks like. I need to find out why dmesg gives this line: WARNING: 1 siblings found for CPU0, should be 2 WARNING: 1 siblings found for CPU1, should be 2 This looks like the reason why my dual Xeon system does not seem to get hyperthreading, even though HT is enabled from BIOS. Bot /proc/cpuinfo and top show only 2 processors. Thanks, Prakash
