Created attachment 208418 [details] kernel config
It looks to me like that module is trying to use symbols just added to 2.6.32-rc6 http://www.linuxhq.com/kernel/v2.6/32-rc6/virt/kvm/kvm_main.c
from your .config: CONFIG_HAVE_KVM=y CONFIG_HAVE_KVM_IRQCHIP=y CONFIG_VIRTUALIZATION=y CONFIG_KVM=m # CONFIG_KVM_INTEL is not set you have enable KVM but distabled KVM_INTEL, you'd better enable KVM_INTEL or disable KVM then install kvm-kmod, mix them is not a good idea, have a try.

This issue was caused by a mismatch of in kernel and out of kernel modules. This has been fixed in the newer kvm-kmod series that I've added to the tree a while back.
