In fact it was Stephan Eisvogel who provided me with this hint.
He has also kindly pointed me to his version of memtest86+ for FreeBSD
that not only has porting changes but also some functional
changes/enhancements as well:
http://seitics.de/pub/memtest/
Stephan has also offered/suggested the following:

I personally think that this sounds cool, especially for certain kinds
of applications.
And just for the reference I am attaching my minimal patch that allows
memtest86+ to compile on FreeBSD. I haven't tested the result though.
I have some doubts about .code32 change in setup.S.
Also I see that Stephan changed memtest.lds so that
. = 0x10000;
became
. = 0xc0120000;
