Can the Fuze do Line-in recording?

No, there is no line input.

Is it known that there is no physical connection between the line-in pins of the AMS 3525 system-on-chip, and the Sansa dock connector?  Has anyone traced the PCBs to figure this out?

From the Sansa Fuze dock connector pinout, I see that there are a large number of pins unaccounted for.  It seems surprising that there are no pins connected to line-in.  (iPods, for example, include line-in on their dock connectors despite the fact that the stock firmware can’t use them… but Rockbox can)
