Yes, I agree.  Perhaps not all of them however; probably not accel=3D and
probably not kvm_type too.  In fact, what I don't like about this patch
is that it doesn't really feel "right" to put it in -machine.  On the
other hand we definitely do not want to split it further to -accel.  Oh
well, it seems like designing the right command-line interface is the
hardest part of doing QEMU.
