Does anybody know if Internet Explorer supports the history.pushState() and history.replaceState() methods for manipulating browser history? Considering these are just being implemented in Firefox 4, I'm not holding my breath, but does anybody know if they're coming in IE9?

Probably the best site for browser compatibility information is CanIUse. Here's the section on history.
Summary - IE9: no, IE10: yes (as of platform preview 3)
The first Release Candidate of IE9 (released 10th Feb 2011) does not support history.pushState or history.replaceState. Generally no new features are added after a product gets to RC stage so it is very unlikely that the final IE9 will support these methods.
Microsoft have a good overview for developers of the features IE9 does have.
Update: Internet Explorer 9 was launched (on 14th March 2011) and definitely does not support history.pushState() or history.replaceState().
Update 2: The current platform preview of IE10 still does not support pushState / replaceState.
Update 3: Platform Preview 3 of IE10 supports the history API! Details
