Ok, maybe it is not required then, but it also doesn't hurt.

Also, when making chunk size configurable we should not leave that
to the confused user but pick a working value automatically, probably
depending on the emulated device.  I can't see what the benefit would
be though, especially given that intel-hda is probably used in most
configurations these days.
