Prefer IPv6 (or: Use AAAA instead of A-records)

Hi,
I have an server with dual-stack, and a client with dual-stack. This server runs Apache2 on a Debian-system, and the server listens to ::80 (only). The client is also a Debian-system. The DNS-server holds an A and AAAA record for this server:
port.burning.hell. 604800 IN A 192.168.10.1
port.burning.hell. 604800 IN AAAA 2001:14b8:16c::1
However, when I point my Firefox to http://port.burning.hell/ it connect to 192.168.10.1. He prefers IPv4 over IPv6. However, if I point it to http://[2001:14b8:16c::1]/ it works without a problem.
Now the strange part: On my Windows XP SP2 host (also dual-stack), he connects via IPv6.
And last, but not least: When I connect to http://noc.sixxs.net, my Debian-client prefers IPv6.
Anyone know why this is happening?

Prefer IPv6 (or: Use AAAA instead of A-records)
According to some discussion glibc prefers local and directly-connected routes, then IPv6 and then IPv4. It is not clear on how to change this behavior though or how it exactly works.

The feature is fixed in glibc 2.5-1 and later:

There isn't a fix for Etch.
