10.6 and working fine here too

I would suspect the problem isn't the application - it's that unnecessary 32-bit device driver that Sony installs. The old version doesn't work with Lion, unless you reboot into 32-bit mode. I suspect they compiled the new version in 64-bit mode which would let it work in Lion but wouldn't work in Snow Leopard unless you reboot into 64-bit mode.

I say the driver is unnecessary because Calibre works fine with Sony devices even when the Sony kernel driver isn't installed.

The only reason the driver is likely needed is to talk to the Sony to authorize it for DRM.

Adobe can write out authorization information to a mass storage device, but Sony's method is more secure. But in reality, they should be using a userland driver for that (load up the driver when the app is running to do the authorization, unload it again).
