Well, I'm not sure whether or not that still would have been the

Did you miss the email where Paul pointed out that Mac/PowerPC
didn't use to do any of this? And apparently never had any issues
with it? And probably worked more reliably several years ago than
suspend/hibernation
does _today_?
Still works pretty reliably; the last time my PowerBook G4 was
rebooted was 6 weeks ago. Once every 60 suspends or so the kernel
USB driver gets really confused and doesn't wake up the USB
controller properly, leading to dead keyboard/mouse, but other than
that I never have problems. I wouldn't be surprised if I could
comment out 90% of the "suspend" code and still have it work, the
hardware in is is incredibly robust. I can even swap batteries while
it's in suspend-to-RAM, as long as I do it in less than 45 sec or so;
I get around 6-7 days of suspend-to-RAM time on a full charge.
Cheers,
Kyle Moffett
