note the 2000001 in the first arg. This doesn't match with
any of the options that we see listed at

http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/uts/intel/sys/x86_archext.h#470

which are used by mcdcfg_csname in
http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/uts/i86pc/io/mc/mcamd_dimmcfg.c#384

This is interesting, because the mobo vendor's documentation
says it is a Socket 754 beast, which is definitely listed in the source.

I think you should log a bug on bugs.opensolaris.org for
this issue.
