OK, http://affenbande.org/~tapas/rtc_wakeup/ is the URL, right?
And LTP might well be a good home for it, I honestly don't know.
I am checking to see if this can be added to the set of tests run in Martin's automated testing. If you haven't looked at this, check out:

This doesn't cover all the various RT variants of Linux, but might focus some attention on mainline latency issues.
