here's something I discovered at http://etatdesieges.com/_assets/scripts/ie6fix/
Googling - I found http://code.google.com/p/ie7-js/
And, the best thing is that it works. We no longer need to not use CSS2 + CSS3 + PNGs for the sake of the 30% of people still browsing with IE6.
I will be installing it on my site for the png support shortly. The HTC fix doesn't work in Ruby on Rails - so this is a huge help.
