Yes, I see that now:

[root at polaris root]# rpm -q --qf "%{ARCH} %{VERSION}-%{RELEASE}\n"  
kernel
ia32e 2.4.21-27.0.2.EL

[root at polaris root]# rpm -q --qf "%{ARCH} %{VERSION}-%{RELEASE}\n"  
kernel-smp
x86_64 2.4.21-27.0.4.EL

However, I wonder why "yum install kernel-smp" chose the x86_64 kernel? 
  Looking in the CentOS update repository, there is no ia32e directory.  
Inside the x86_64 directory, I see the following kernels:

kernel-2.4.21-27.0.4.EL.ia32e.rpm
kernel-2.4.21-27.0.4.EL.x86_64.rpm
kernel-smp-2.4.21-27.0.4.EL.x86_64.rpm
kernel-smp-unsupported-2.4.21-27.0.4.EL.x86_64.rpm
kernel-unsupported-2.4.21-27.0.4.EL.ia32e.rpm
kernel-unsupported-2.4.21-27.0.4.EL.x86_64.rpm

Why is there no kernel-smp for ia32e?  Based on the current kernel's 
behavior, I guess it's safe to assume the UP kernel will work for SMP, 
but why isn't it labeled accordingly?  Is this just an oversight by the 
package maintainers?  It would be great if someone could post a FAQ 
regarding these kernels for CentOS 3.4.

Thanks,
