qemu wants to raise that limit. the old driver had a limit of 64hz
unless you used the override. The new driver doesn't seem to have
this check. It's arguable that it should, and it too should
have a sysctl though.
so if I understand correctly this driver has hardcoded limits that can't be
changed from userspace (yet) ?
