Without having looked at your code; 
Specifying the doctype and and/or xml prolog changes the rendering behaviour from strict to quirks mode (or the other way around) for IE; this will mess up many css options.

See eg. : http://www.cs.tut.fi/~jkorpela/quirks-mode.html or http://www.quirksmode.org/css/quirksmode.html
