I believe that all the packages related to glibc, e.g. libc6, are at 
2.7-10ubuntu3 for 8.04. Which begs the question, did you unwisely enable 
the hardy-proposed repository? Or am I barking up the wrong tree here?


If so, how can I downgrade?

Out of my league, I would assume, that if you have enabled 'proposed' 
and you need to regress to hardy, as you say, 'standard', you're going 
to have to understand apt's capability to 'pin' packages, either 
individual packages, or wildcard pins on packages (yikes!). The only 
experience I've had with 'downgrading' (hardy-backports->hardy) was a 
complete failure.

Hope I'm wrong about hardy-proposed,
