I have learned just recently that Opera (and apparently also Mozilla, and
maybe IE) use a "quirks mode" to display CSS 'broken' (i.e., broken in the
way that people composing it on browsers with broken CSS expected it to
look), and that the !doctype tag is necessary in your document to signal
that you expect it to display properly.

You can use this bookmarklet:
in Opera to show whether the page shown is in quirks mode or not.

I havnt tested how compatibility modes work, nor do I know whether you
tried it, but it's possible that this may have contributed to your
problem.  [Although I spose on rereading this now that 'completely
ignoring' the CSS may be a sign of a different kind of problem...]
