IE6 feature detection - possible solution

IE6 feature detection - possible solution


In order to transition away from $.browser to $.support, people are
going to want/need something to help identify IE6.
After a bit of research, I found one property that seems to work:
elem.style.maxHeight. IE6 returns undefined.
I'm adding a patch to support.js - please let me know if you think
this would work. I tested in IE6 & 7, Firefox 2 & 3, Opera 9.5 & 9.6
and Safari 3.
Usage:
if (!$.support.maxHeight) {
    // do ie6 stuff
}
