I have verified that by downloading and upgrading to the following kernel the issue is resolved, the issue still exists with 2.6.38-10

I successfully booted from CD on RHEL 5.4 and Centos 5.5 on CD and installed with no issue with 8 cpu's

Here is the text of the commit I think fixes the issue.

    KVM: fix kvmclock regression due to missing clock update

    commit 387b9f97750444728962b236987fbe8ee8cc4f8c moved kvm_request_guest_time_update(vcpu),
    breaking 32bit SMP guests using kvm-clock. Fix this by moving (new) clock update function
    to proper place.
