In my opinion, that should be okay, but I'm also using IPv6

Hmm, if no one is screaming about any space issues and not wanting
to have IPv6 installed, I guess it should be fine to have the IPv6
code built-in, shouldn't it?
Screaming? No, but it would be good to see what the cost in space was
before comitting it.
The old 2.4 kernel left ~1.5M fee on my linksys, the 2.6 one redices it
to 800K, so space is,
or will soon become, an issue, and it's a still a (largely) IPv4 only
world out there.

Injecting myself into this conversation: "it's still a largely IPv4
only world out there" will continue to be the case as long as user
devices are not ubiquitously IPv6 capable: that's a truism.
I've had to deal with similar circular reasoning when trying to get
various packages out there to support DSCP packet marking: the claim
being from application vendors (including the OSS community) that
"networks don't support DSCP/QoS". In my conversations with ISPs and
IXCs, I hear the rational, "we don't deploy QoS support because not
enough applications leverage it to make it worth the (not
insubstantial) incremental cost".
Since the software cost on the user side is a lot cheaper (and more
scalable), let's break the deadlock/chicken-and-egg-dilemma there...
I think enabling IPv6 in the default kernel config does not help IPv6
adoption in any way, all it does is annoy people that only use IPv4,
because it wastes precious flash space.
Even with the default binary builds of OpenWrt, IPv6 can easily be
enabled simply by installing a few packages. What's really missing is
IPv6 support on the ISP side, as well as an implementation of DHCPv6
that doesn't suck.
