kvm segfaults on 2.6.36-64bit kernel with 32 bit userspace

qemu-kvm 0.12.5 and 0.13.0 from debian and compiled from sources segfaults for me on a vanilla 2.6.36 64bit kernel and debian squeeze 32bit userspace.
Doing a bisection resulted on commit 9581d442b905 (KVM: Fix fs/gs reload oops with invalid ldt), reverting it fixes the problem and survived a new debian-amd64 install.

Fixed upstream (c8770e7ba63bb5dd); patches to be posted for 2.6.36.
