Oh, ok.  The MC146818 doesn't even have a register E, and we check 
register D for RTCSD_PWR on a read anyway, so 0x0e is just RAM, and 
finding any bits set there makes atrtc_setup_clock fail - as it did!

I doubt the former, but the latter is true :)  I was reading isa/atrtc.c 
to a) try working out how to do the wakeup-on-timer thing and b) tracing 
ct_to_ts and ts_to_ct messages re another problem - both other topics.

sorry, Ian
