Hi Lance,
I'll have to defer a number of the below questions to other people since
I do almost all of my work on Linux. But I'll answer what I recall.

Something is coming back to me about this. In Linux/BSD, we do memory
mapped I/O from userspace to do the KCS. However, in Solaris,
apparently this is not allowed and you can only do the I/O via a driver.
So it would suggest that the driver is required, but I am not a Solaris
expert in any way.
Is it possible you're looking at the "default" outputs from ipmi-locate
and not an actual discovered KCS device?

Last I recall, the KCS driver is what is used by people on FreeBSD for
FreeIPMI. But again, I'm not sure if the userspace KCS driver is
"legal" on Solaris. Presumably a OS kernel driver would have to be
written.
