That may sometimes be the case but, well, not with some of the hardware
I have had. Let me assure you that there are, out there, plenty of
laptops where the BIOS will hang, hard, trying to suspend to disk, or to
restore from it.
Really. I know, four out of five machines I have had that didn't work
successfully with suspend-to-disk, that was why.
Unless there was something I was missing beyond setting up the partition
with phdisk (or whatever the tool for the hardware was) and getting it
to happily suspend and resume from that partition under Windows...

Y'all don't have an Australian office, by any chance?

Yeah, that will, indeed, suck mightily. Having seen the code that
implements APM, though, as well as some of the other Phoenix BIOS
code... I can't say that I am surprised it's buggy. Messy does not even
start to cover it...

Yup. World of pain. :)
We have nothing to lose because we don't have anything.
