Specifically for Comcast, the majority of their customers rent their modem
from Comcast, so they have the benefit of being able to control that to
some extent.  I fairly sure I remember reading somewhere that all of the
DOCSIS 3 modems they provide support IPv6.  In many areas (eg, the SF Bay
area where I live) 100% of their rented modems are DOCSIS 3, and they are
even phasing out DOCSIS 2 for non-rented modems.

For people buying their own, the majority of the modems they support also
do IPv6, but as you say it's not all of them - based on
http://mydeviceinfo.comcast.net/, about 3/4 of their supported modems do
support it.
