The simplest method which springs immediately to mind is to create a
shared library containing dummy versions of relevant functions (e.g.
DPMSQueryExtension, XF86MiscSetKbdSettings etc) then point LD_PRELOAD
at the library. E.g.:
$ cat hack.c
Bool DPMSQueryExtension(Display *display, int *event_base, int *error_base)
fprintf(stderr, "*** DPMSQueryExtension called by %s\n", program_invocation_name);
$ gcc -c -fPIC hack.c
$ gcc -shared -o libhack.so hack.o
$ export LD_PRELOAD=`pwd`/libhack.so
$ xset q >/dev/null
*** DPMSQueryExtension called by xset
