So the battery runs out you will have resume from disk (25 sec in my HP laptop)
If the battery has the power it will resume from RAM (< 5 sec)

Cool - tuxonice looks like a bunch of kernel patches right now. I'll have to investigate altering an OEM install CD to include them.
I have a suspend to both function already in this kernel (2.5.24). Suspend to disk already works. Suspend to both is what fails. Mind you, the cold-boot time (power on to useable desktop is 25-30secs anyway - the "instant up" provided by suspend-to-ram is nice.)
This leads to the possibility of implimenting a pseudo-suspend script - something that will shut down high-drain stuff (screen, wireless, what else?) and bring them back up... but not actually a full suspend. This would save power (not as much as a full suspend), be more easily implimented on systems with dodgy acpi (so it's better than nothing) and still provide that instant-on availability.
In other words - it provides the feeling of a suspend, with some of the advantages...
