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.
