"Conditional commenting" seems to be the way to go, though mention of them
on this list over the past few days has been my first sight and so I don't
know what kind of cross-platform compatibility they have. There was an email
to the list about an hour ago that gave an example of Conditional
<!--[if IE 5]>
... which might work. Either that, or something like
... which is only understood by the newest browsers.
