In fact, I was working on the same topic of support SDT markers. But I started it by adding support for accessing arguments in uprobes [1]. The patchset is floating around the list for now but I hope it'll get merged soon. I guess you want to have it too :). Anyway, it'd great if you add me to CC next time.
