I passed your comment to NOMACHINE. Below is their answer:

==============
After that point in the nxagent sources, "query" makes the agent
ignore the layout info and fallback to a simple copy of client keymap.

The purpose of option "query" is to force nxagent to copy the
keyboard map of the connected client. In that case there is
no need to compile a keymap basing on the layout information
(model, country, etc.): if the client presents e.g. a German
keyboard the agent will copy and use that keyboard.

So it would work for any country.

This is different from the Linux case where keyboard option
would be "pc105/de": in that case the agent would compile its
own keymap on the basis on the info "model=pc105" "country=Germany".

We use "query" for Mac client since a long time, because we found
there wasn't correct keyboard map files to build a key map
for Mac layout in the X Windows systems istalled on the majority
of Linuxes.
==============

I think we need to try it. To my understanding, we need to patch
the OpenNX osdep.c file around line 688:

#if 0 // ifdef __WXMAC__
     if ((_kbd[0] == '\0') || strstr(_kbd, "empty")) {
         strncpy(_kbd, getMacKeyboard(), sizeof(_kbd));
     }
#endif

and replace there getMacKeyboard() by "query". The change is easy
and worth trying in view of the above information from NOMACHINE,
but at present we stuck on compiling OpenNX under Lion 10.8 (see
details about failing to compile OpenSC in my previous post). Can
anyone help please?

Thanks,

Sergey
