Another CSS Workaround Technique for IE5.x/Win

Tantek’s Mid Pass Filter:

the Mid Pass Filter is a filter which passes external style sheets to version 5.x Internet Explorer for Windows browsers, but not to earlier/older browsers, nor to newer / more modern browsers

The benefit of this approach is that you can isolate your IE5.x/Win CSS workarounds in a single stylesheet, keeping your main stylesheet for other browsers a little cleaner. Found via Zeldman.
