I gritted my teeth :)

I grabbed the source for xorg-server-1.3.0 from Gutsy (the next  
Ubuntu release) and the latest Intel driver from the git repo at  
intellinuxgraphics.org. You need at least xorg-server-1.3.0 to build  
the Intel driver.

That all built and installed cleanly. I rebooted and everything  
worked - albeit with the same sync polarity issue I had with the  
stock Feisty drivers.

So I did a really ugly thing: everywhere in the Intel drivers that  
the sync polarity is set I forced it to be +H/+V. Built, installed,  
rebooted and - magic! - I get a nice crisp display. It works.

If it'd be helpful I'll take a little time to understand the proper  
way to fix it and submit a patch?

Thanks for pointing me in the right direction.
