Here is the Kconfig/Makefile patch I used to build ehca as a part of linux build.

I put out a initial set of files (as discussed) on openib.org svn.
The Kconfig option will follow when I've verified that it really compiles as is in svn.
The same set with makefiles and install scripts is available from sourceforge as ehca2_0033
