The fscscy driver was not ported to Linux 2.6 yet. There was a first
request one year and a half ago:
http://lists.lm-sensors.org/pipermail/lm-sensors/2006-February/015319.html
http://lists.lm-sensors.org/pipermail/lm-sensors/2006-March/015489.html

Nobody volunteered yet to do the work. I've added your request on our
wiki/Devices page, but don't hold your breath. The FSC Scylla is an old
and rare chip, it's unlikely that anyone will volunteer to port it for
free.

The Scylla chip (as all other hardware monitoring chips) has a number
of sensor inputs (voltages, temperatures and fans). It has no idea what
these signals correspond to nor where they do come from. This really
depends on how the manufacturer wired the chip on the motherboard. So
the general answer is that no hwmon driver specifically handles
redundant PSUs because they don't have to.

lm-sensors is heavily based on procfs on Linux 2.4 and sysfs on Linux
2.6. As BSDs don't have anything like that as far as I know, there
really isn't anything to port. I seem to remember that one of the BSDs
has support for a limited number of popular hardware monitoring chips,
but the implementation is completely different. Anyway, this is really
a question you want to ask on a BSD list if you want a more accurate
answer.
