Err. With link local addresses you MUST include the interface
explicitly (either %ethX or -I eth1). Otherwise it makes no sense, 
the kernel has no way of knowing what interface you wanted to use, 
you should use global ipv6 addresses (and corresponding routing entries).

elinks http://[fe80::204:23ff:fe5b:ce53%eth1]/ works for me btw..
Then again, rfc3986 doesn't seem to even allow that syntax, so it working
is probably even a "bug" and firefox etc. are right.
