Pretty much got everything working now I think.
Disabled frontpage extensions because I don't think tehy're used, and was worried that they were a security risk.
Not sure how Sad handled redirecting from the old root of the site (www.sadgeezer.com/) to the new postnuke powered site (www.sadgeezer.com/html/) but I've put something in place that seems at least functional for now.

Currently running something of a hybrid version of postnuke.. I think we were running something like 0.7.2.3 but the replacement files I uploaded came from the latest build 0.7.5 and I had to upload the header.php file from 0.7.2.6 (the only other copy I had lying around) as the newest version seems incompatible with our themes.
