SBS, the company I work for, has recently built a dual PPC 750CXe board in an
ATX form factor called Adirondack that has a VT82C686B on it. I'm SBS's Linux
software engineer and I've ported Linux 2.4 to the Adirondack. The port is in
the linuxppc_2_4_devel tree.

Yes! Nail right on the head!

How many existing PPC-based machines incorporate one
of those kitchen-sink southbridge chips like the VIA
VT82C686B that are normally found in x86-based machines?

A lot of them. Hardware developers for high-end PPC embedded designs
like them as a way to get UARTs, PIC, and IDE in one dirt-cheap package.
Software developers hate them because they are evil.

Once they've used them once, the hardware engineers think they're evil
as well. But I did get a 7410 system with a Via 686a up and running the
2.4-devel kernel. I think all the necessary fixes have percolated into
the main tree, except for one MIDI fix which is only in Alan Cox's kernel.

It may or may not be worth noting (depending on exactly how you meant
this question) that even PowerMacs contain the functional equivalent
of chips like the VT82C686B. They're Apple custom ASICs and provide
Macintosh style I/O ports, but do generally cover the same area of
functionality as a PC southbridge.
