Sorry to be a pain, but I currently do not have access to IE7, any chance you could run this through and do a quick check for me?
looks fine to me...in fact the only difference between IE7 and Firefox is that the
<li> your vcard is nested in has a visible bullet in Firefox, but not in IE7
Also your blue square bullets in 'skills summary' are slightly off centre (too high).
You can always use IE8's 'compatibility mode' to view pages with the IE7 rendering engine - it's the 'broken page' icon in the top right next to the refresh button.
