Yes. These changes will NOT AT ALL fix the AAAA timeout problem. But some
people reported there were "other" (unspecified?) issues than AAAA timeout.

glibc 2.5 (and kernel 2.6.17.2) will fix a bunch of other potential
IPv6-related inconviences:
It will not cause connection timeouts when trying to connect to a
dual-stack server from a dual-stack private-IPv6(ULAs) and IPv4 network,
as IPv4 will be attempted first.
Similarly, if you have sone clueless XP/Vista box advertising a 6to4 prefix
on the network: glibc 2.5 will prioritize IPv4 (unless the final destination
has a 6to4 address), whereas glibc 2.3 would prioritize IPv6.
