Hi,

I see that various Silicon Image 6xx (CMD) chipsets are supported
by pciide_cmd_reg.h.  Unfortunately the SiI680 isn't among them.
It's an UDMA/133 PCI-IDE controller, with optional RAID
(see http://www.cmd.com/products/overview_sii0680.asp).
Is someone working on it?  FreeBSD 5.x seems to support it, so
their driver may be a start for figuring out things.
