Thanks Nate.  I nearly clipped that part of the diff, figuring only the 
<*_MASTER> messages had changed, but I now see ata1 devices differ too.

Have similar regressions re ATA been turning up elsewere, do you know?

I've been digging, still on the trail of those t_delta messages, but now 
figure these might be spurious, some timecounter missing/gaining a tick 
or something, if ATA is maybe what's hanging meanwhile?

There's no HD light activity at all from resume button/switch through 
that 60 second wait, when 15? seconds after the third t_delta line is 
written to console, the HD light flashes while apparently simultaneously 
writing the rest of the resume messages, and it comes alive.

Guess I should next upgrade the 7.0-R slice to 7.2-STABLE to find out if 
this problem has been mfc'd :)

cheers, Ian
