Has anyone managed to find a Windows 7 RC x64 compatible driver for the Sony Firmware Extension Parser (SFEP) on the Sony Vaio VGN-NS20S/S?

I've checked the Action Center again and this time the solution details contain instructions for users in Europe, not just the US and Brazil. I downloaded the suggested file from Sony Europe and updated the driver for my Unknown Device. It installed without errors and I now see Sony Firmware Extension Parser Device but it doesn't seem to have fixed the brightness shortcut keys. Interestingly the filename is the same as the one I tried before (SFEP Driver (Sony) 8.0_09Q1_O - 8.0.0.1.zip) only this time it definitely does include x64 drivers. Either I was going mad before and didn't notice them, or they've updated the package to include x64 drivers.
