Position Is Everything has just published an article by me that
should be of interest to people on theList.
It's titled "In Search of the One True Layout" and explains how you can:
* display columns (as many as you like) in any order
* have equal height columns without having to use faux columns
* align elements vertically across columns
* do all of the above at the same time without having to litter your source
code with presentational markup

where you can find some examples (doh!) including an interactive demo
that let's you have a play with the techniques.
Plus there's a new take on the old favourite, the holy grail of css
layouts aka 3 columns liquid center, fixed width sides:
