Looks OK.  Does FF and IE pass this test (aka do we know it's a valid test?)

FF passes.  It returns a float for the top and bottom that is ~31.55.

I don't know about IE.  Levi or Emil, do either of you guys have a windows machine?  Or know where I can rdesktop into one?

It'd be handy if you uploaded the layout test itself for easy testin' :)

There is no gap between the divs (the gap being the root cause of the problem on ebuyer.com) on either FF or IE.  Oddly, the top div on IE extends into the bottom div.

Webkit:
top.bottom = 29
bottom.top = 31

FF:
top.bottom =~ 31.35
bottom.top =~ 31.37

IE 8/9:
top.bottom = 32
bottom.top = 31
