IE shows transparency - with a lot of work:

[system = mac]
page.10.marks.LOGO = IMAGE
page.10.marks.LOGO.file = fileadmin/image/logo/logo.png
[useragent = *msie 5* ]
page.10.marks.LOGO = IMAGE
page.10.marks.LOGO.file = fileadmin/image/logo/logo2e.gif
[browser = msie6 ]
page.10.marks.LOGO = HTML
page.10.marks.LOGO.value (
<div id="ie_logo" style="position:relative; height:65px; width:210px;
filter:progid:DXImageTransform.Microsoft.AlphaImageLoader(src='fileadmin/image/logo/logo.png',sizingMethod='scale');"></div>
)
[else]
page.10.marks.LOGO = IMAGE
page.10.marks.LOGO.file = fileadmin/image/logo/logo.png
[end]

you have to use this filter. Then IE handles alpha-transparency correct. 
BUT not IE Version 5  :-(

good luck with all these conditions
