Alternate Box Model Hack

Hi,

While reading up a bit on the famous Box Model Hack, I found this solution
proposed:

selector {
property: standard-value !important;
property /* IE<6 */: ie-box-model-value;
}

It will feed "ie-box-model-value" to IE<6 and "standard-value" to all
others. This seems to me to be the most elegant solution to the box model
problem but I wonder where possible drawbacks might be. One website
mentioned that this code would "break Konqueror on Linux". Does it mean
Konqueror gets the wrong one of the two values or will it crash or
something? Also I have noticed that Opera 7, in its small-screen mode (only
there!), assigns too small widths (when this hack is used on widths), but
I'm not sure if it is really caused by this hack. (It seems to ignore any
widths specified later for this selector, except for width: auto - always
with "!important" of course.)

Any comments?
