replicated with your configuration, but can't still reproduce it with mine
even when forcing as you do

  CONFIG_KVM=y
  CONFIG_KVM_INTEL=y

available from :

is this the configuration for the host kernel?

if you want to use the last code for kvm you should have CONFIG_KVM disabled
and instead use the external module as instructed in (HINT: you don't have a
patched kernel) :

  http://kvm.qumranet.com/kvmwiki/HOWTO1

not sure which version will be part of 2.6.24 but I suspect it might not be
kvm 59.
