Apparently some machines need to use DVOA, so I expect we'll see some bug 
reports now that this has been pushed.  Since other machines need DVOB, we'll 
probably need to autodetect this situation somehow (VBT maybe?) or, failing 
that, add a new quirk.

Is that something you can do, Hong?  According to Keith, X30 is one machine 
where DVOA is needed.
