If this is a strictly "hardware" discussion, v6 "works" on a variety of
models, albeit not with stock firmware.
To wit : http://www.dd-wrt.com/wiki/index.php/IPv6

This suggests that Cisco (et.al.) can release an "official" firmware
image to support v6 on existing devices whenever they're sufficiently
motivated to do so. I'd wager the only reason it hasn't been made GA is
to limit the number of "pass-the-buck" support calls that start at $isp
and get bounced back saying "we don't support that yet, call whoever
makes your router".

Not necessarily.  dd-wrt lacks the memory expense of the silly web
interface that Linksys is oh so fond of implementing in their consumer
grade boxen. I suspect that adding features to the Linksys code may
be a bit tighter on image and data space than dd-wrt's "stripped down"
efficiency.

For cheap access points, we run OpenWRT on something like a 32M/8M
WRT54G-TM, and there's never been a problem with memory, even after
adding somewhat piggy (for embedded) stuff like ntpd.  Of course, the
normal platforms are a bit more cramped.

It's apparently very easy to add IPv6 to OpenWRT, and you can opt to
include or exclude things like a web interface.  It's fairly competent
and can support things like multi-SSID.  Good place to start if you're
used to a UNIX shell environment and Linux.  

Anyways, the point is, a lot of the heavy lifting has already been done
to make multiple IPv6 firmwares for many of these devices.
