I just tried Bitkeeper's 2.4.0-test8 rsynced yesterday morning.  X
(still using XFree 3.3.6) locked up on me this morning so I moved
back to a kernel built with Paul's  2.4.0-test6, but I saw this exact
problem while I was running -test8 (and last week with -test7, which
also locked up on me):

Aug 30 09:50:01 c22234-c kernel: pmac_set_rtc_time: got 3 byte reply
Aug 30 09:51:00 c22234-c kernel: pmac_set_rtc_time: got 3 byte reply

etc., once per minute.

This is on a Performa 6400/180.  I don't see it in Paul's test6.  It
doesn't seem to be a real problem except for the excessive logging,
since the clock seemed accurate (xntpd is running).  Does anyone know
what's happening and how to shut it up?  CONFIG_PPC_RTC was n for all
of these kernels.
