For anybody following updates the the Liferay theme I released:
Theme now looks correct in IE7 and IE8.
IE6 is functional, only sub color schemes (to do with selectors in the color scheme css), and png images need work.
Added extra option in templates/init_custom.vm:
$custom_places = true ## will replace the communities/my places menu with a simplified view hiding any public community view from non community owners. (Beta feature added to simplify the my places menu for sites that only use private pages)
Head tag also employs google chrome frame if enabled for better rendering in IE6.
Update can be installed now via the software catalog directly in Liferay.
