Could you check the patch? I can confirm that that patch, which is the same as qemu-kvm commit 249cdd049c7976614ad46eb86409d5e1e53835cc works for me when enabling KSM in the kernel. You need to build-depend on libc6-dev >= 2.10.2-1 or define your own MADV_MERGEABLE value, though. I only tested the patch against 0.11.0+dfsg-1, though, rather than kvm-88!
