I think you'd find the image-flash goes away if you make the logo.gif the background image of the #header h1 element & not the "a" element.
I've done this myself and it's totally resolved the problem w/IE. Of course, it really is an IE bug so I can completely understand if you wouldn't want to change it.

Jake - I took the liberty of looking at your stylesheet & found this:
#header h1 a {
background: transparent url("/rsrc/img/logo.gif") no-repeat;
}
