It does work in F-12, the response for the lack of support in F-13 was 'deal with it'. There is suppose to be a patch to emulate it in the kernel but apparently it won't go upstream until its a generic infra patch that can allow support of other emulated bits in other cpus in a generic way. So its possible it will come back, but I don't hold up hope of a quick resolution. Which leaves us in a big predicament as to how we're going to support the 1.5 million odd XO-1s out there moving forward.
