There is a proprietary plugin called "Neptune" which says that it will allow you to use IE Tab functionality in Chrome on Windows.
Meadroid do this because they have ActiveX controls which they have written and they want them to be able to work in any browser, and they explicitly mention Chrome in the list of supported browsers for enabling ActiveX with this.
There is also a modified version of Chrome, called ChromePlus, which includes IETab, among other extra features.
I've not used either of these personally, but they look like they'll do what you want. I'd be interested to hear if they work out for you, as I know of other people who want to be able to use IEtab in Chrome :)
