I wouldn’t use any Internet Explorer version+1
like your effort, really looks good
I fear you are whistling into the wind though, like one of the comments mentioned the problem isn’t really IE6 , it is the IT departments, etc who look after the systems put on user pcs. if this dept chooses to stay with whatever software for their own reasons, then you as the user have no choice, especially if you are not allowed to d/l your own s/w.
we as individual users use the modern browsers of our choice, we don’t have someone telling us that we cannot do this or do that. most times in business, you ain’t got no choice. that I understand and agree with.
the other problem is that IE6 is a resource used by lots of users who would never ever come to this site or any other site like this, they are users, not web developers or designers, and could care less about this end of the business. I am sure most of them could not even tell you that they were using IE6 and that most of them would have no reason to know anything about browsers like FF, Chrome or Safari. when you do something like what you are doing with this page, you are preaching to the converted, not the unconverted.
anyhow, good luck with the campaign, but IE6 is still a reality not a dream and may remain so for longer than we wish
