I was trying to find this info a while ago, too. When I replaced the
Solaris Xsun Xserver with XFree86, an xmodmap in our system that used
keycodes was no longer working. The problem was that XFree86 was
translating the scancodes into different keycodes than Xsun was. This
happened with both the openwindows (Solaris) and XFree86 versions of
xmodmap, and also using the openwindows xlib. So I concluded that the
scancode to keycode translation must be happening in the keyboard driver
used by XFree86. I never found the source of this - I fixed my problem by
changing the xmodmap to use the more portable keysyms, rather than
keycodes.
I'm guessing that the XFree86 keybaord driver lives in
xc/programs/Xserver/hw/xfree86/input/keyboard. After a quick look in here
and the files that it includes, I couldn't find what you are looking for,
but it might be a place to start, if you haven't already looked at this.

OK, after some more resarch, I have some idea of what's going on. It seems
that the X server gets the scan codes from the kernel, then passes these
scan
codes to the X client. xlib has some nice functions to then convert these
scan codes into keycodes, then into keysyms. (Correct me if I'm wrong
here.)
So, I looked into xc/lib/X11/XKeysymDB, which seems to have the kind of
information I want, but not the actual scan codes I'm looking for. Then I
looked at xc/include/keysymdef.h, which seemed to be a better place. But
after looking at these, they both seem to be keysym definitions, not scan
code (or even key code) definitions.
Where are the scan codes defined, or mapped or whatever?
Thanks for any pointers?
