Photoshop Elements :: Scanning Negatives With OpticFilm 7600i Negative Scanner

I'm looking for a way to scan directly into PSE 10 with my negative scanner. Maybe a plug-in? I know it's unlikely that there's something to convert the image to positive etc but I'd rather spend time doing that than use the bundled software with the scanner (SilverFast). However, currently Get From Scanner gives me "Film Scanner" which either previews and scans black negs or doesn't work at all without Silverfast installed. Seems the only way to set it up as a TWAIN scanner (yep, got TWAIN plug-in) is to use a seperate piece of software like silverfast which is then launched to get the scan. Got correct and up-to-date drivers properly installed.
