$(DLOPEN_LIBS) is empty on Solaris, since dlopen() is in libc, so I never

Well, it already works :)
probe process("/usr/bin/Xorg").mark("request__start")

Since Xorg binary is -rws--x--x here (Fedora), you have to be root.
Being in the stap group is not enough.
I'm going to make a nice tapset and propose it for inclusion when it's
ready (might take some time since I learn autotools, git, systemtap and
rpm packaging in the process ;-)
