The mkimg step is missing from the instructions on the wiki, as are the
arguments to makefs to get it to include some spare inodes in the image.
I haven't yet found any way to pass boot-time arguments to the kernel
(qemu's -append option doesn't seem to work, or I'm passing the
arguments wrong) so the root fs has to be on ada0s1a.
This comes up successfully with qemu-devel-2.0.2_3. The 'malta' machine
seems to be rather limited (one CPU, no more than 256M memory); I might
see if I can get a kernel config that works with one of the other qemu
machines.
