yeah, but dyngen is gone now. So tcg really stands for "whatever qemu
does", in here.

After this revision, I must say I'm less happy with the name "accel".
It's really a cpu model. I'm even thinking about changing the name of it
to QEMUCPUModel or whatever. (suggestions welcome)

So "default" or "qemu" would be good choices IMHO.
