Even if Solaris can dynamically load/unload most of the modules, all the
modules still executes in the same monolithic kernel content, so I think
it's different from the concept of micro-kernel, which allows some basic
kernel functions(memory mamagement, etc.) to be executes within
different processes.

Please correct me if I'm wrong.
