You can turn off ipv6 on interfaces. This should not prevent bridging

I wish I'd known this. Could you give an example of how to remove ipv6
functionality from an interface? I think this was the only thing preventing me
from unloading an accidentally-loaded ipv6.ko module.
There are no accidents. It's your userspace which triggers it loading.
And what is it actually that you are trying to fix? It smells more
like you have a bug in your environment.
On most Linux distributions and default installations, the ipv6 module
gets automatically loaded either on startup or when certain utilities
try to probe ipv6 entities or test for ipv6 connectivity, even when you
haven't configured any ipv6 interfaces. It's nice to be able to unload
the module to free up memory and make netstat and other programs' output
prettier. Prettier in the way that you don't have extraneous output
that's meaningless when there are no ipv6 addresses configured.
It's impossible to unload the ipv6 module when there's even one
interface with ipv6 functionality enabled, even when the interface is
administratively disabled/shutdown.
