Some googling suggests it's actually a JMicron controller that is decent and
fairly well supported by 6.2-STABLE. Can anyone confirm that?

Yes, JMicron controllers are a pretty standard feature of most modern
Intel-based boards. Mine works without any problems:

I do find it odd that they would use discrete chips for the NIC and extra
SATA ports, when the chipset contains both.

Mainboard manufacturers usually like to offer Parallel ATA, which is
not available in newest Intel chipsets, hence there is a need for an
external chip. I guess, Serial ATA comes as a bonus with such external
chips, and also provides the user with more choice on which controller
to use.

Also, I don't think ICH8 southbridge has integrated Ethernet
networking capabilities -- these are usually added as an external
chip, connected by PCI Express, as the following diagram illustrates:
