Better late than never ehh..
As I said, no ETA yet as I don't know just how far off the sd card stuff
is, but it's in the todo pile. In the meantime, I'll keep an eye out here
which I am ~certain we haven't been doing so far. I've added QEMU stuff
to my build/test scripts now that I've got the direct kernel boot working
for me so hopefully once things get fixed, they'll stay that way.

Thanks,
Conor.
