After the second thought, I don't think MSIE is doing black / white. They're taking the XOR on the screen.  Consider the following HTML:

<body style="padding: 10px; margin: 0px; background-color: black;" contenteditable>
<div style="width: 100%; height: 50px; background-color: white;"></div>
<p style="position: absolute; top: 15px; left: 15px;">inside P</p>
</body>

When you move the caret to inside P, you see black caret but with your patch, the caret will be white.  What we really need to do here is to obtain the bitmap from the screen and XOR it to make caret's bitmap.  At least that's what MSIE and other applications do on Windows.  This probably needs to be done at platform level rather than in WebCore because each platform has its own way of creating caret.
