That will be up to the people doing the rendering. For maps rendered on 
  Wikimedia servers (see http://meta.wikimedia.org/wiki/OpenStreetMap), 
CC-BY-SA would seem like an obvious choice, but it's up to them.

I have just updated that FAQ. It was referring to an early out-of-date 
draft of the ODbL.

I'm not sure if this has been discussed yet, but I don't see any reasons 
for changing it.

Compatibility with open content licenses has been an important point for 
us in working with ODC. One of the changes in the latest ODbL draft was 
made "in order to remove any possible concerns about license 
compatibility on Produced Works". We believe that ODbL now is fully 
compatible with licenses such as CC-BY-SA or GFDL for rendered maps.
